Solr documents of custom content properties are removed from index when node is reindexed

[alexanderjakab]

Since ASS 2.0.1.5 the indexation of custom content properties was reintroduced by setting the property solr.enableIndexingCustomContent to true.

On a node update in the alfresco repository the solr-documents for that node is reindexd. Those for the custom content properties are removed for one reindex cycle. This leads to a different behaviour than the reindexation of all other node properties ...

the search results for the custom content properties simply disappear for one reindex cycle. from an enduser perspective this leads to inconsistent searchresults and the impression of a defect in the default search behaviour

can be reproduced by using the following sdk sample project.
alfresco-sdk-sample-reindex-content-properties.zip

1. build sample project with maven and start acs with run.sh start
2. call sample webscript from your browser : http://localhost:8080/alfresco/s/sample/helloworld
   now a test node was created here "/app:company_home/cm:test/cm:test.txt". it has 1 custom content-property acme:metadataIndex. you can verify in your node-browser
3. use the nodebrowser so search for the node: aftsQuery: "acme:metadataIndex:Alexander" and you will find the node as expected
4. call the sample webscript again
   on an already existing node - the cm:name property will be changed to cm:xtest.txt leading to a reindex
5. use the nodebrowser so search for the node: aftsQuery: "acme:metadataIndex:Alexander" . after solr tracks the update the result will disappear.
6. keep searching ... after 8 sec. it will appear again

• reference to hyland support case: #00838836
• initial github issue - leading to reintroduction of custom content property indexation : Custom ACS 7.2 ContentModel Properties of type "d:content" are not indexed with ASS 2.0.3 #403
  seems to be related to : https://alfresco.atlassian.net/jira/software/c/projects/MNT/issues/MNT-23525
  and changes made here: c3dd096

This is fixed in:
MNT-23669: Custom d:content indexes becomes temporarily unsearchable when any property on the node is updated
It was released as a hotfix in Search Services 2.0.5.2 and will also be part of the upcoming 2.0.8 SP release.
