I am just learning ES and would appreciate a quick explanation on analyzed
vs not analyzed searches. My basic understanding is that unless indicated
otherwise, fields are analyzed during indexing time but when it comes to
search time, a term query matches documents for terms that are not
analyzed, hence it must match exactly. I am not sure what that means
exactly because for one, the fields are already analyzed and tokenized
during indexing time, secondly, when I execute a term query, it only
matches in lowercase but with match or query\_string queries, they are case
insensitive. Any insights will be much appreciated.
Thanks,
Bob

Oh I think I get it now, the analyzed value in the index is all lowercase
and hence the exact match must be lowercase for an exact match using term
query. When using match query, the term is first analyzed making it
lowercase before doing the search, hence case insensitive. Am I right?

Correct. A term query does not analyze the terms, while a match query does.
Generally, you should use text queries on non-analyzed fields, and match
queries on analyzed ones. Analysis does not always mean lowercasing terms,
but that is what the default (standard) analyzer does. All these concepts
derive from Lucene.

Ivan

Correction: meant to say use _term_ queries on non-analyzed fields, not
_text_ queries.

Yep, thanks for confirming my understanding, in the case of using term
queries on non-analyzed fields, the search value must match the exact case
of the original value if I understand this correctly.
