This is a request for comment.
CC Android supports 2 kinds of searching:
- full search: one that uses close to the full expression capability of calibre (e.g., authors:foo and series:bar)
- simple search: one that uses search terms without a lookup name prefix, where the search is limited to the fields title sort, series, authors, and tags.
The simple search is much (!) faster than the full search because it can use the database instead of looping through the books one by one to evaluate the expression.
I am considering changing CC to allow the user to add other fields to the simple search field list? This would make CC more like calibre, where in calibre Search preferences a user can enter a list of column lookup names that are searched when using non-prefixed names.
The benefit: the user can extend which columns are searched, making it possible to use simple search on custom columns.
The negative: yet another mysterious option somewhere. Changing the text in the search box might help. For example, the current text "Simple search: words only; look in title, authors, series, and tags" could become "Faster search: words only; look in fields selected in Settings / Grouping Drawer / Fields for simple search."
The question: would anyone actually use this feature if it appeared?
