recoll is a local search engine based on Xapian:
   http://www.lesbonscomptes.com/recoll/

   By itself recoll does not offer web or API access,
   this can be achieved using recoll-webui:
   https://github.com/koniu/recoll-webui

   As recoll-webui by default does not support paged JSON
   results it is advisable to use a patched version which does:
   https://github.com/Yetangitu/recoll-webui/tree/jsonpage
   A pull request was sent upstream, if this is merged the patched
   version is no longer needed

   This engine uses a custom 'files' result template

   set base_url to the location where recoll-webui can be reached
   set dl_prefix to a location where the file hierarchy as indexed by recoll can be reached
   set search_dir to the part of the indexed file hierarchy to be searched, use an empty string to search the entire search domain

long suggestions now wrap around the box instead of going overboard.
