Description
Searches could be more expressive if there was the option to search for a value "in this field, OR in that field". Currently multiple fields in search requests are handled as AND only.
The implementation uses a naming convention such that if you want to search in field 'a' or in field 'b', you send the parameter 'a_OR_b'. You could also add more fields like that e.g. 'a_OR_b_OR_c'.
Not for all fields it's possible or desired to do this; fields for which this doesn't work are northBL, southBL, eastBL, westBL, relation, without, phrase extTo, extFrom, featured, template, and the Range Query Fields. If they are part of a _OR_ parameter, they are ignored.
Multiple _OR_-containing parameters may be sent, also in combination with AND-parameters (that do not contain _OR_ in their name).
