Hi, I think I can answer to some of them but one is also unknown for me, how to make an AND search: - it seems that it is searched for whole keywords and not for substrings. Is that true?No, you can seacrh for aster* and you will get the results if it finds asterisk.- it seems that only keywords of a length that is at least 4 characters. Is that true?That is true, as you already know- keywords are OR-combined in the search. Is it possible to combine them with AND?Yes, the way you do it is adding a + before each word with no spaces, for example+Licensing +rds +timewill look for tickets with all the words in it- it is only searched for the full keywords. Is it possible to search for substrings?sorry, but I do not know the difference with the first question- is it possible tor search for strings instead of keywords?yes, you can search for "RDS licensing" and you will get results of that string, you just have to add the " at the beginning and at the endI have not tested all possibilities but they are well explain here:https://dev.mysql.com/doc/refman/5.5/en/fulltext-boolean.htmlfor example:+apple
-macintosh: Find
rows that contain the word “apple” but not “macintosh”. By the way the searches are no case sensitive.Hope this helps
