Closing card as it appears to (largely) duplicate functionality already deployed.

As a cataloger, I need the ability to locate resource descriptions in the collection by searching on title. 

In scope

For this card, index 'Main Title' and 'Other Title' fields for the Instance entity only. 

• Keyword indexing on Instance title fields for Monograph

• Phrase indexing on Instance title fields for Monograph

• Simple search queries (as listed below in use cases)

Out of scope

• Variant Title, inclusive of 'Main Title' and 'Other Title'

• Parallel Title, inclusive of 'Main Title' and 'Other Title'

• Title normalization

• Left anchor searching

• Indexing Work entity

• Multiple language indexing

• Compound search queries (e.g. nested queries, queries that exclude specified search terms)

Use cases   

     1.  CQL 'all' - single search term

       Simple keyword searching of title index

       The following queries are equivalent, and each require that both the term "x" is included in the title for a resource description. The queries should return the same result sets.

      title all x

      title all "x"

    2.  CQL 'all' - multiple search terms

       Simple keyword searching of title index

       The following queries are equivalent, and each require that both terms "x" and "y" are included in the title for a resource description without specifying the order in which the terms are present in the title. The queries should return the same result sets.

      title all "x y"

      title all "y x"

    3. CQL 'any'

       Simple keyword searching of title index

       The following queries are equivalent. The condition requires that either search terms"x" or "y" is included in the title for a resource description. And the search queries return the same result sets

      title any "x y"

      title any "y x" 

     4. CQL simple phrase  

       Simple phrase searches the title index for search query terms in a precise order

       The following queries are not equivalent.

      title == "x y"

                  --> the resource description includes the phrase "x y" in the correct order anywhere in the title

      title == "y x"

                 --> the resource description includes the phrase "y x"  in the correct order anywhere in the title

     5. CQL exact phrase 

       Exact phrase searching of title index

       The following queries are mutually exclusive

      title ==/string "x y"

                  --> the title for the resource description matches "x y" exactly                   

      title ==/string "y x"

                 --> the title for the resource description matches "y x" exactly

CQL operators could have modifiers that change search behaviour
