How can I specify a search by an exact field value?
> FT.CREATE idx1 NOHL NOFREQS SCHEMA f1 TEXT NOSTEM > FT.ADD idx1 doc1 1 FIELDS f1 aa.bb > FT.ADD idx1 doc2 1 FIELDS f1 aa > FT.ADD idx1 doc3 1 FIELDS f1 cc.aa This search returns all 3 documents because "aa" is recognised as a term in all of them.
FT.SEARCH idx1 @f1:aa
But in my case I may have thousands of “aa.bb” and a few “aa” mixed in between them. How can I query only those where f1==“aa”?
Note that some of SQL mappings [here](https://oss.redislabs.com/redisearch/Query_Syntax.html#mapping_common_sql_predicates_to_redisearch) are incorrect in this sense. E.g. *@x:foo* and *WHERE x='foo'* have different semantics.
