Thank you. I attached a screenshot of Relevanssi search plugin. Here is quite good idea when you choose AND operator as default and the search finds no matches, it will automatically do an OR search. Google does the same and shows under every result Missing: <striked out search term>. I use this plugin for search in groups titles. All these titles are addresses of buildings, so it’s important to get houses in results with exact street name and number. Now i get results from different streets with same number. Will be waiting for an update and thank you.
Kind regards,
Gintas
