Searches with : don't work as expected

[liowalter]

There are several cases where a searches with ":" in the middle is expected to work. But this is not always the case.

	description	simple search	simple search with “”	advanced search	advanced search with “”
Linear : algebra	simple search	not ok	? less results than "linear algebra"
MKB PP 305 : 27,2004	call number	not ok but this is fine	ok	ok	ok
10.1023/A:1008433817832	doi	not ok but this is fine	not ok	not ok	ok
urn:nbn:ch:bel-bau-diss108444	urn	not ok but this is fine	not ok	not ok error	ok
RETROSoai:agora.ch:hnu-001:1917:23::141	id	not ok but this is fine	ok
author:dicker	"expert" search	ok	ok

Involved in this process are these parts :

• https://github.com/swissbib/vufind/blob/master/module/VuFindSearch/src/VuFindSearch/Backend/Solr/LuceneSyntaxHelper.php#L526

[vufind] Searches with : don't work as exepected

[liowalter]

Astonishingly the parser for the ISSN/ISMN/DOI/URN advanced search was not set to edismax.

On top of that, the doi_isn_mv and urn_isn_mv were not included in the simple search.

Changing these both things yield the following improvements :

	description	simple search	simple search with “”	advanced search	advanced search with “”
Linear : algebra	simple search	not ok	? less results than "linear algebra"
Linear:algebra	simple search	not ok but it works on core	ok
MKB PP 305 : 27,2004	call number	not ok but this is fine	ok	ok	ok
10.1023/A:1008433817832	doi	ok	ok	OK	ok
urn:nbn:ch:bel-bau-diss108444	urn	not ok	ok	not ok no more error	ok
RETROSoai:agora.ch:hnu-001:1917:23::141	id	not ok but this is fine	ok

Hi Lionel, thanks a lot for fixing it. As you already mentioned: It might happen that an Index error caused by wrong spelled field-names leads to a bunch of documents not being indexed which are part of a whole batch request sent to SOLR by the indexer client. But we can test it especially before the next Gesamtexport.

Another idea came to my mind: Now you are using a field type text_untreated valid for indexing and query use cases. What if you would define a new field type which is only valid for for indexing puposes and not for the query execution?

Not sure if this works but a fast test might be helpful
