Essential Non-Google Search Tools for Researchers – Top Tips

This is the list of Top Tips that delegates attending the UKeiG workshop on 7th September 2016 in London came up with at the end of the training day.  Some of the usual suspects such as the ‘site:’ command, Carrot Search and Offstats are present but it is good to see Yandex included in the list for the first time.

  1. Carrotsearch http://search.carrotsearch.com/carrot2-webapp/search or http://carrotsearch.com/ and click on the “Live Demo” link on the left hand side of the page.
    This was recommended for its clustering of results and also the visualisations of terms and concepts via the circles and “foam tree”. The Web Search uses eTools.ch for the general searches and there is also a PubMed option.

  1. Advanced Twitter Search http://twitter.com/search-advanced
    The best way to search Twitter! Use the Advanced Search http://twitter.com/search-advanced or the click on the “More Options” on the results page. There is a detailed description of the commands and how they can be used at https://blog.bufferapp.com/twitter-advanced-search 
  1. Yandex http://www.yandex.com/
    The international version of the Russian search engine with a collection of advanced commands – including a proximity operator – that makes it a worthy competitor to Google. Run your search and on the results page click on the two line next to search box.

    Alternatively, use the search operators. Most of them are listed at https://yandex.com/support/search/how-to-search/search-operators.xml. There is also a /n operator that enables you to specify that words/phrases must appear within a certain distance of each other, for example:

    "University of Birmingham" nanotechnology /2 2020

    There are country versions of Yandex for Russia, Ukraine, Belarus, Kazakhstan and Turkey. You will, though, need to know the languages to get the best out of them and apart from Turkey they use a different alphabet.

  1. Millionshort http://millionshort.com/
    If you are fed up with seeing the same results from Google again and again give MillionShort a try. MillionShort enables you to remove the most popular web sites from the results. The page that best answers your question might not be well optimised for search engines or might cover a topic that is so specialised that it never makes it into the top results in Google or Bing.Originally, as its name suggests, it removed the top 1 million but you can change the number that you want omitted. There are filters to the left of the results enabling you to remove or restrict your results to ecommerce sites, sites with or without advertising, live chat sites and location. The sites that have been excluded are listed to the right of the results.
  1. site: command
    Use the site: command to focus your search on particular types of site, for example include site:ac.uk in your search for UK academic websites. Or use it to search inside large rambling sites with useless navigation, for example site:www.gov.uk. You can also use -site: to exclude individual sites or a type of site from your search. All of the major web search engines support the command.
  1. Microsoft Academic Search http://academic.research.microsoft.com/
    An alternative to Google Scholar.“Semantic search provides you with highly relevant search results from continually refreshed and extensive academic content from over 80 million publications.”This was recently revamped and although it now loads and searches faster than it used to the new version has lost the citation and co-author maps that were so useful. It can be a useful way of identifying researchers, publications and citations but do not rely on the information too much. It can get things very wrong indeed. For example, I’ve found that for some reason the affiliation of several authors from the Slovak Technical University in Bratislava is given as the Technical University of Kenya!
  1. Wolfram Alpha https://www.wolframalpha.com/
    This is very different from the typical search engine in that it uses its own curated data. Whether or not you get an answer from it depends on the type of question and how you ask the question. The information is pulled from its own databases and for many results it is almost impossible to identify the original source, although it does provide a possible list of resources. If you want to see what WolframAlpha can do try out the examples and categories that are listed on its home page.
  1. OFFSTATS – The University of Auckland Library http://www.offstats.auckland.ac.nz/
    This is a great starting point for locating official statistical sources by country, region or subject. All of the content in the database is assessed by humans for quality and authority, and is freely available.
  1. Meltwater IceRocket http://www.icerocket.com/
    IceRocket specialises in real-time search and was recommended for inclusion in the Top Tips for its blog search and advanced search options. There is also a Trends tool that shows you the frequency with which terms are mentioned in blogs over time and which enables you to compare several terms on the same graph.

    Very useful for comparing, for example, mentions of products, companies, people in blogs.

  1. Behind the Headlines NHS Choices http://www.nhs.uk/news/Pages/NewsIndex.aspx
    Behind the headlines provides an unbiased and evidence-based analysis of health stories that make the news. It is a good source of information for confirming or debunking the health/medical claims made by general news reporting services, including the BBC. For each “headline” it summarises in plain English the story, where it came from and who did the research, what kind of research it was, results, researcher’s interpretation, conclusions and whether the headline’s claims are justified.

Alternatives to Google: Carrot Search and eTools.ch

Two of the services I cover in my workshop for researchers on alternatives to Google are Carrot Search and eTools.ch, and recently one of the people who had attended the session in April asked me to confirm what Carrot Search used  to provide its main results. Strictly speaking, neither Carrot Search nor eTools are Google free: eTools is a metasearch tool that has Google as one of its sources and Carrot Search uses eTools for its web search. At the start of the year, Carrot Search offered 7 options for searching under tabs across the top of the search screen including Web, “wiki”, Bing, News, Images, PubMed and Jobs. Web search used eTools.ch to provide the results.

The range of options has now been reduced to just three: the more transparently labelled eTools Web Search, PubMed and Jobs.

This makes sense as the number of accesses to Bing via the api was always limited and I could never get the news or images options to work. eTools in any case is a metasearch engine covering 17 tools including Google, Bing and Wikipedia so the extra Carrot Search tabs did seem to be unnecessary. The full list can be seen on the eTools home page.

This is where it gets interesting. It appears that Carrot Search does not just copy the results from a search on eTools.  I ran a search on Brexit in Carrot Search and compared the results from eTools Worldwide and eTools United Kingdom. All of the sets  were different so Carrot Search must be doing some additional analysis and processing.

Carrot Search doesn’t just list the results but also organises them into topics or Folders that are displayed on the left hand side of the screen. These can be a useful way of narrowing down your search.

Carrot Search offers two other ways of displaying results: Circles and Foam Tree.

Carrot Search Foam Tree
Carrot Search Foam Tree – 13th July 2016

Both show the density of terms in the top 100 results and allow you to click on an area to add the term or phrase to the search.  In addition I am finding that the Foam Tree is an interesting way of monitoring changes in news coverage and social media discussions on a topic, product or company. Yesterday, when I ran the search on Brexit, there was an area representing Theresa May.  Today, that had been replaced with one for David Cameron. I assume that is because the news coverage has been concentrating on David Cameron’s last day as Prime Minister and his last Prime Minister’s Questions (PMQ) in Parliament . Later he goes to see the Queen to officially resign as Prime Minister. Tomorrow,  with Theresa May as our new Prime Minister and a new Cabinet, the Foam Tree could have a very different structure so I shall be looking at it periodically to see if and how it reflects changes in events.

As I mentioned earlier eTools.ch, which is behind the main Carrot Search web search, is a metasearch engine covering 17 tools. It also has options to select a country from a drop down list (Worldwide, Swtzerland, Liechtenstein, Germany, Austria, France, Italy, Spain,  UK) and a language (All, English, German, French, Italian, Spanish). Either or both of these give you completely different views and opinions on a subject.

It is a convenient way of gathering a range of foreign language information, especially on European events, and is easier than searching individual country versions of Google or Bing. The disadvantages are that the range of countries and languages is limited and many of the articles will not be in English. Nevertheless, I often find it helpful at the start of a piece of research as I get a general feel for the type and range of information that is available.

Carrot Search and eTools.ch are just two of the tools that I cover in my workshop on alternatives to Google. If you are interested in finding out more, the next session is being organised by UKeiG and will be held in London on Wednesday, 7th September 2016. Further details are available on the UKeiG website.
