Oops... I wasn't reading carefully enough - frequencies and positions only
relate to tokenized fields (text) - not string fields.
That doesn't impact your ability to do AND and OR of discrete string terms
of a multivalued string field.

Yes, but it is simply doing an AND or OR of the individual terms - no
phrases or implied ordering of the terms.

Jack,
Thanks for the explanation! :
We have a multi-value field as following:
<field name="label" type="string" indexed="true" stored="true"
multiValued="true"/>
Most of these labels are two or more letter phrase e.g.
1) Google Reader
2) Google Mail
3) Google Cloud Storage
etc. etc.
if we add omitTermFreqAndPositions="true" to this field:
<field name="label" type="string" indexed="true" stored="true"
multiValued="true" omitTermFreqAndPositions="true"/>
Will we be able to execute queries like:
label: (Google Cloud Storage) ?
Thanks.

how
frequently the terms occur or that some terms may be in present in
phrases.
So, you can do AND and OR for individual terms in that field, but not
phrases, and there is no scoring difference whether a term occurs once or
a
thousand times in that field for each document. A lot less information
needs to be stored in the index.
