Lack of interest Search forums filter logic (AND/OR)

[findozor]

Im using search forums and love this functionality but found some issues that imo dont let me use it how i want

1. 1st thing is tags - when adding few tags for example red and blue i suggest to filter and show threads either having red or blue tag or both tags together. right now adding few tags doesnt work this way. can you add option to show threads having tags with both OR / AND logic?
2. prefixes - if im adding tags and prefix together feels same thing. its filtering only threads does have filter AND tag both strictly . Its impossible atm to filter threads with prefix OR having tags. more flexible filtering needed
