Search the local Everything index. query supports Everything syntax (ext:pdf, size:>1mb, dm:today). No path means all indexed locations. Returns paths, size bytes and modification times. Pagination reflects a live, changing index. Does not read file contents.

Count matching indexed files/folders without retrieving their paths.

Check ES version and Everything IPC connectivity. No changes to the service.

Search filenames using ES regular expressions, e.g. ^报告.*.pdf$.

Filename matching: subsequence (约指南 matches 约会指南), substring, or unordered keywords. Literal characters are escaped; use search_typo for spelling errors.

Match full pinyin, initials or mixed Chinese/pinyin against a bounded ES candidate page. heteronym enables alternative character readings. Continue next_candidate_offset until candidates_exhausted; not an exhaustive global result before that.

Match the entire literal basename, including extension. No wildcard interpretation.

Match all/any literal filename keywords and exclude literal words; words containing spaces remain phrases.

Match full basename using * (zero or more characters) and ? (one character). Other characters are literal.

Search a documented extension category. Explicit filters.extensions overrides the category's default extension list.

Browse indexed children (not a filesystem listing). recursive=False returns direct children; missing index entries are not included.

Rank a bounded page of filenames by SequenceMatcher similarity (0..100). Not semantic search. All matches on the page returned; ranking is page-local. Continue next_candidate_offset for remaining candidates.
