search: prevent pathname related conditions from removing "stop words" Before this revision, pathname related conditions below cause unintentional ignorance of "stop words". - path:,extension: (for "File contents" or "File names") - added:, removed:, changed: (for "Commit messages") Therefore, pathname related conditions with "this", "a", "you", and so on are completely ignored, even if they are valid pathname components. To prevent pathname related conditions from removing "stop words", this revision explicitly specifies "analyzer" for pathname related fields of SCHEMA and CHGSETS_SCHEMA. Difference between PATHANALYZER and default analyzer of TEXT is whether "stop words" are preserved or not. Tokenization is still applied on pathnames. This revision requires full re-building index tables, because indexing schemas are changed.
