Subject Re: Indexing non-stored fields
Date Tue, 01 Jul 2014 00:15:20 GMT
Thanks for the quick response.

Follow-up newbie question:
If the fields are not stored, how is the server able to search for them
after a restart? Where does it get the data to be searched?

Example:  "bob" (firstname) is indexed but not stored. After initial
indexing, I query for "firstname:(bob)" and I get my document back. But if
I restart the server, where does the server go to retrieve information that
will allow me to query for "bob" once again? It would seem that "bob" got
stored someplace if I can query on it after a restart.

My untrained mind thinks that searching for "firstname:(bob)" (after a
restart) will fail, but that searching for "recordid:(12345)" (in my
original example) will succeed since it was indexed+stored.

(stored + indexed makes total sense to me; it's the indexed but NOT stored
that I can't get my head around).

Thanks!
