Search Strings

Do you want to follow a specific topic in the news? Is a certain emerging issue vital for you and your business? Build a search string on an ongoing topic. We have made some sample search strings for you that you can use and adapt to your wishes, or that you can use for inspiration when building your own search string. Bird Flu Search String

atleast2(bird flu! or h5n1) and hlead(bird flu! or h5n1) and length>300 and pub(economist or the guardian)

Explanation of the search string:
With this search it is not necessary to use more search terms. However, if you would only use bird flu! or h5n1 virus, you would retrieve too many results. To make sure you get articles with relevance to the topic, it is better to fine-tune the search. In the example above the search has been fine-tuned by adding that the search terms have to appear at least twice in the article and that the terms have to appear in the title or the first paragraph of the article. You can also add a minimum length of an article, which will usually increase the chance of finding a relevant article.

Explanation on using elements in the search string:

bird flu or h5n1:

You can replace these terms with any other language terms you prefer. E.g. vogelgriep or h5n1 or gripe aviar or vogelgrippe! or aviaria

atleast2(bird flu! or h5n1):

With atln you indicate that the words between brackets have to appear the number of times that is mentioned instead of the n. In this case, twice.

hlead(bird flu! or h5n1):

With hlead you indicate that a certain search term or terms has to be present in the title or the first paragraph of an article.


The length command helps you to exclude small articles. Use length(>n). You can also use this command to find shorter articles with length(

and pub(economist or the guardian):

A good way to manage the number or returned results is to indicate from which sources you would like to extract articles. You can do this by adding: and pub(source name or source name). Vice versa is also possible: and not pub(source name or source name). Elections in the US Headline(election) and (politic! w/s democrat! or republic!) and atleast2(candidate) And country(United States #90plus#) and subject(ELECTIONS & POLITICS)

Explanation of the search string:


With the command ‘headline' you can search the headline of an article.

(politic! w/s democrat! or republic!):

The ‘w/s' command determines that the search terms mentioned after the ‘w/s' need to be within a sentence of the terms mentioned before it. You can also replace the ‘s' with a digit (0 to 255) or ‘p' for within a paragraph. In this example we have placed an ‘!' after the terms to let LexisNexis search for any word beginning with either politic, democrat or republic, this will retrieve not only politic but also politician or political or politics. Off course you can replace the terms for other parties.


When you want a certain search term to be retrieved more than at least once, you can use the command atln. On the place of ‘n' you can fill in a digit for the number of times a search term must at least be found.

country(United States #90plus#):

When you want to narrow you search to a certain country you can use the command ‘country'. This will only retrieve articles that have the indexed term for the specified country. In this example we have also added a relevancy score to the search term. This can be done for all index terms. Within the new LexisNexis platform you can select the index terms from a list, this gets placed in a extra box beneath the query and are not able to place the term in to the query itself. You are also no longer able to set the relevancy score, but are able to search for ‘Strong References Only' by checking the box underneath the index terms box.


LexisNexis adds index terms to articles. These terms are also searchable by using the command ‘terms'. You can look up index terms by using the function ‘add index terms to your search'
