charset

doc_stats

ib_vector_t* fts_index_cache_t::doc_stats

Array of the fts_doc_stats_t contained in the memory buffer.

Must be in sorted order (ascending). The ideal choice is an rb tree but the rb tree imposes a space overhead that we can do without

index

dict_index_t* fts_index_cache_t::index

The FTS index instance.

ins_graph

que_t** fts_index_cache_t::ins_graph

Insert query graphs.

sel_graph

que_t** fts_index_cache_t::sel_graph

Select query graphs.

words

ib_rbt_t* fts_index_cache_t::words

Nodes; indexed by fts_string_t*, cells are fts_tokenizer_word_t*.
