Changes

#* We could index the pathnames into each line, denormalizing, and always search on lines. That would make those easy to AND together. We don’t even need to mget the files afterward as with parent-child relationships, since every line contains the full path (but not icon or encoding—important? Probably not, if highlighting works, which it should without parent-child.). We could even support search-by-color: just index all the green stuff into an array stored as a separate property of the line. (Highlighting would probably have to be done app-side.)

# Build routine to extract trigrams from regexes. (There is no existing work apparent in Python. We could require re2 and call through to its <code>Prefilter::Info::TakeMatch</code> etc., but it doesn't look too hard to implement or too CPU-intense (when you start from the sre_parse.parse() in stdlib); I'd have to do some work in any case to bridge Python to that C routine; and fewer build steps, git submodules, and build-time checkouts make for a lower contributor support load.) Add trigram indices for lines and switch to a filtered query for regexes. Deploy.
