Metacat

Add code to handle query for the http solr server.

Use a new class to handle the solr query engine description request.

Add double quotes to surrend the user or group names in the access fq. This will fix the issue if the names have white spaces.

Add the access query filter.

Allow use of server-side XSLT for SOLR queries that include "wt=<qformat>". https://projects.ecoinformatics.org/ecoinfo/issues/5812

Allow null SM.submitter (per schema). There were null values in cn-dev (and probably elsewhere since it is technically allowed in the schema. But with a null value, we need to have a null Subject for the SM.submitter field, not a Subject with a null getValue() return. Encountered this when testing for: https://projects.ecoinformatics.org/ecoinfo/issues/5929.

add space to prevent syntax error when additional clause is appended. https://projects.ecoinformatics.org/ecoinfo/issues/5929.

CHange replication 'update' query to use a LEFT JOIN so that the performance of the replication update action is improved, which had been causing an HTTP timeout for large metacat installations. See https://projects.ecoinformatics.org/ecoinfo/issues/5929.

Add the code to read the index field information from the schema.xml.

Add code to handle the solr index information. we still need to figure out how to get the information.
