How do i pressure the wordpress search show only the result using the full word no with negligence words.
I am much less sure the way you would manage that, however, you take an alternate route and employ a wordpress plugin similar to this one.
Try WordPress › Search Unleashed « WordPress Plugins after which tweak your research form to incorporate "" round the search phrase to come back just full word hits.
Wordpress Search, despite plug ins, is terrible. I suggest building out a custom implementation of Google Custom Search Engine for the site.
It's pretty simple to integrate effortlessly with Wordpress also it blows away Wordpress search engine results both in simplicity of use and precision of results. It will possess a small cost connected (between $100 and $250 annually, for those who have a little to medium-sized site), but it's totally worthwhile.
