FP commented on JSPWIKI-1131:
-----------------------------
Hi [~juanpablo],
I built commit 9406f01b338a643e37ea124ef8d5e794d709859b and was able to
pinpoint the issue to the use of `VersioningFileProvider` as page provider.
* The steps below were all executed on the same page: `TestLucene`
* The data directory only contained the wikipages-de at the start of the test
* Lucene index was rebuilt before starting the test
||Version before||Action||Version after||Searches||
|–|Create page and add "correct"|1|"correct": ✔|
|1|Add "horse"|2|"correct" ✔ "horse" ✘|
|2|Add "battery"|3|"correct" ✔ "horse" ✔ "battery" ✘|
|3|Add "staple"|4|"correct" ✔ "horse" ✔ "battery" ✔ "staple" ✘|
* It seems that the indexer does not pick up the latest version of the file
but the version before. The file TestLucene.txt in JSPWiki's pages directory
always contains the correct (=latest) version of the page and the corresponding
files in `OLD/TestLucene` seem to be correct, too.
* The following debug log entries are recorded when after adding "horse" (=
row2):
{code:java}
DEBUG org.apache.wiki.WatchDog - JSPWiki Lucene Indexer: Entering state
Emptying index queue, expected completion in 60 s
DEBUG org.apache.wiki.search.LuceneSearchProvider - Updating Lucene index for
page 'TestLucene'...
DEBUG org.apache.wiki.search.LuceneSearchProvider - Indexing TestLucene...
DEBUG org.apache.wiki.providers.CachingAttachmentProvider - Listing attachments
for WikiPage [Wiki:TestLucene,ver=1,mod=Mon Nov 09 11:04:08 CET 2020]
DEBUG org.apache.wiki.providers.CachingAttachmentProvider - LIST from cache,
TestLucene, size=0
DEBUG org.apache.wiki.search.LuceneSearchProvider - Done updating Lucene index
for page 'TestLucene'.
DEBUG org.apache.wiki.WatchDog - JSPWiki Lucene Indexer: Exiting state{code}
Some additional notes:
* Search works as expected, once I switch from `VersioningFileProvider` to
`FileSystemProvider`
* The setting `jspwiki.usePageCache` (true in may case) does not change the
behavior.
* The setting `jspwiki.lucene.indexdelay` does not change the behavior.

> Key: JSPWIKI-1131
> URL: https://issues.apache.org/jira/browse/JSPWIKI-1131
> Project: JSPWiki
> Issue Type: Bug
> Components: Search
> Affects Versions: 2.11.0-M7
> Environment: * Debian 10
> * Tomcat 9: 9.0.31-1~deb10u2
> * OpenJDK-JRE 11: 11.0.7+10-3~deb10u1
> * JSPWiki 2.11.0-M7
> Reporter: FP
> Priority: Critical
> Fix For: 2.11.0-M8
>
> Attachments: exception.txt, illegal-page-name.txt
>
>
> It seems that the lucene search index is not updated when a user edits an
> existing page or creates a new page. In both cases, the page is not found
> when someone searches for it.
> Search works as expected when:
> * Tomcat is stopped
> * The files in the {{lucene}} directory are removed
> * Tomcat is started
> * Wait until the Lucene Indexer thread finishes reindexing
> The following exception occurs when a page is edited (full stack trace
> attached):
> {{java.io.NotSerializableException: org.apache.wiki.WikiContext}}
