Function ParseSearchFilters

src/TextClient.cpp:152–197

Strip optional --type / --extension / --avail / --min-size / --max-size flags from `args`, leaving only the search keyword(s). Each flag takes exactly one whitespace-separated value. Unknown tokens are preserved as part of the search query, joined by single spaces in input order. Returns true on success, false if a flag is missing its value or a value fails to parse; on failure the output values a

// Returns true on success, false if a flag is missing its value or a value
// fails to parse; on failure the output values are undefined.
