IT is a very short word and the search we do is not for 1:1 matches, but for words that can start, end and contain the string. That's why you get Villa road Suite there . Suite has it in it. If you want to have 1:1 match for words, then you'll have to hack the code that does the search query.
Is this what you want to do? However then you'll most probably run in another issue - if you have the word "something-it" then the query won't match. as it is part of the word.
Or search only for Security... The first thing is Cyber Securty which is very strange... The whole search plugin is a mess... If this can't be fix we will look for other solution which sucks because i need to redo the whole system now
With this change you should be able to search for 1:1 match for words. Keep in mind that if you enter "Information technology" for search term, then you'll search for the full word "information" or "technology".
It would be really good if you do those changes in a hotspots plugin. We have a onAfterBuildQuery event that would give you the current query object. There you could strip the current where part of the query and do whatevery you want. This way even when you update hotspots your changes to the json.php file won't be overriden.
