           Summary: Searching for URIs in MARC fields could be improved
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement

In Zebra we currently have this index:
  <index_subfields tag="952" subfields="u">
    <target_index>uri:u</target_index>
  </index_subfields>
It seems to be connected only to items.uri however. The generic index name
would suggest a broader range. Or perhaps, allow a broader range?

We still have one other specific uri indexed:
  <index_subfields tag="024" subfields="a" condition="marc:subfield[@code='2'
and text()='uri']">
    <target_index>Identifier-other:u</target_index>
  </index_subfields>

Two popular MARC fields for URIs, 520$u and 856$u are not indexed in a specific
index.

How about adding them to uri ?
Since we do now have uri bound to items, do we need a specific subindex (like
item_uri) for that one? Or the other way around, given that uri is already
taken, why not add generic_uri or any other (better) new index name?

And still elaborating here, a urx search does not really work in Koha. Several
special characters in URLs seem to return nothing, since C4/Search does not
like them probably. (While the search works in yaz-client.)

Should we make it possible to search those just like other text fields too? If
I am looking for a record containing a URL like sub.domain.country, why not
look for a word in the string like sub or domain?
