feat(search): add search by title/content index and tag at the same time (#978)

* feat(search): add search by title/content index and tag at the same time

* fix(search): set search type to basic and remove tag from term for proper highlightning and scroll when searched by tag and title/content index

* fix(search): use indexOf to find space so it is easier to read

* fix(search): trim trailing whitespaces before splitting

* fix(search): set limit to 10000 for combined search mode (to make filter by tag more accurate)
