This implements a fulltext-search feature for linked PDF files.

search

All linked pdf files are indexed using Apache Lucene. Search-results are displayed in a google-esque fashion in an additional tab in the entry editor (visible only if a fulltext search is active).
Users can enable/disable fulltext-search with a toggle-button in the search-bar.

  • Change in CHANGELOG.md described
  • Tests created for changes
  • Screenshots added (for bigger UI changes)
  • Manually tested changed features in running JabRef
  • Check documentation status (Issue created for outdated help page at help.jabref.org?)
  • If you changed the localization: Did you run gradle localizationUpdate?

I checked the documentation at https://github.com/harawata/appdirs. Magic string jabref is OK for me here.

Im still not convinced with using the literal JabRef for index path and would like to talk about that in the call tonight. I wonder, if there isn't a better, more generic solution.

I agree, especially because it is used in two distinct files and needs to be identical. However, I see how it is also problematic to use the one stored in JabRefFrame. Maybe we should define a new static variable in PdfIndexer?

Result of call - we looked up https://lucene.apache.org/core/8_0_0/core/org/apache/lucene/store/NIOFSDirectory.html

NOTE: NIOFSDirectory is not recommended on Windows because of a bug in how FileChannel.read is implemented in Sun's JRE. Inside of the implementation the position is apparently synchronized. See here for details.

For now, we accept that and think, no issues occur.
