Initialize a Lucy::Simple object.
void lucy_Simple_Add_Doc( lucy_Simple *self, lucy_Doc *doc );
Add a document to the index.
uint32_t lucy_Simple_Search( lucy_Simple *self, cfish_String *query, uint32_t offset, uint32_t num_wanted, lucy_SortSpec *sort_spec );
Search the index. Returns the total number of documents which match
the query. (This number is unlikely to match
A search query string.
The number of most-relevant hits to discard, typically used when “paging” through hits N at a time. Setting offset to 20 and num_wanted to 10 retrieves hits 21-30, assuming that 30 hits can be found.
The number of hits you would like to see after

A SortSpec, which will affect how results are ranked and returned.
