Solr configuration to match multiple object property values

[acotiuga]

Hello all,

Given the static list [foo, foo bar, foo/bar] property of an object (XWiki.TagClass), I would like to get all the documents that have any of these terms in the object and to also highlight all the occurrences in the search results, excluding any other object type that may contain any of these terms.
I do not necessarily need to have a facet for the Tag so I only added property.XWiki.TagClass.tags in queryFields, in DOCUMENT, in Main.SolrSearchConfig.

'queryFields': {
    'DOCUMENT': 'title^10.0 name^10.0
                 doccontent^2.0
                 property.XWiki.TagClass.tags^5.0
                 objcontent^0.4 filename^0.4 attcontent^0.4 doccontentraw^0.4
                 author_display^0.08 creator_display^0.08
                 comment^0.016 attauthor_display^0.016 spaces^0.016',
    'ATTACHMENT': 'filename^5.0 attcontent attauthor_display^0.2',
    'OBJECT': 'objcontent',
    'OBJECT_PROPERTY': 'propertyvalue'
  },

In the following image, which can be easily reproduced by adding the above customization and searching for foo term, the matching sequences are identified as individual tags in the Objects section, but only the exact matching is displayed in the Tags section.

I am looking for a way to make the Tags section to display all the results that are displayed in the Objects section.
I hope that I managed to make myself clear and maybe somebody has a clue about how to achieve this.

Thanks,
Alex

I am looking for a way to make the Tags section to display all the results that are displayed in the Objects section.

We can add a new source for searching the tags in Global Administration: Search Suggest, and customize the query for it.

Looks a bit mess, but it works
name platform.search.suggestSourceTags
engine solr
service Solr Suggestestion Service
query

qf=property.XWiki.TagClass.tags:foo
qf=property.XWiki.TagClass.tags:foo bar
qf=property.XWiki.TagClass.tags:foo/bar

limit 3
highlight & activate are activated

@nikpetrenko this doesn’t seem to help with my problem. I still can’t see all the related terms in the tags section

Thanks!

Yes, because objcontent and property.XWiki.TagClass.tags are indexed differently. If you enable debug mode on the search you’ll see that:

• the generated query is different for objcontent and property.XWiki.TagClass.tags:
  • objcontent_en:foo | objcontent__:foo
  • property.XWiki.TagClass.tags__:foo | property.XWiki.TagClass.tags_string:foo | property.XWiki.TagClass.tags_en:foo | property.XWiki.TagClass.tags_boolean:F
• the matched fields are:
  • 0.058886815 = weight(property.XWiki.TagClass.tags_string:foo in 2) [SchemaSimilarity], result of:
  • 1.9084475 = weight(objcontent_en:foo in 2) [SchemaSimilarity], result of:

Then, if you check the Solr schema, you’ll see that these two matched fields are indexed differently:

• objcontent_en is indexed as text_en, see xwiki-platform/xwiki-platform-core/xwiki-platform-search/xwiki-platform-search-solr/xwiki-platform-search-solr-server/xwiki-platform-search-solr-server-core/src/main/resources/conf/managed-schema at xwiki-platform-14.8 · xwiki/xwiki-platform · GitHub . For this field the value “foo bar” generates 2 tokens, “foo” and “bar”, which explains why searching for “foo” matches “foo bar”
• property.XWiki.TagClass.tags_string is indexed as string, see xwiki-platform/xwiki-platform-core/xwiki-platform-search/xwiki-platform-search-solr/xwiki-platform-search-solr-server/xwiki-platform-search-solr-server-core/src/main/resources/conf/managed-schema at xwiki-platform-14.8 · xwiki/xwiki-platform · GitHub . For this field the value “foo bar” generates a single token, “foo bar” which is not matched when searching for “foo”.

So the reason you see only “Tags: foo” is because only that tag is matched by the “foo” search.

Thanks @mflorea!
