If you use the suggested solution, it will detect the words at indexing
time.
However, Solr's FilterFactory's lifecycle keeps no track on whether a
file for synonyms, keywords etc. has been changed since Solr's last startup.
Therefore a change within these files is not visible until you reload
your core.
Furthermore keywords for old documents aren't added automatically if you
change your keywords (and reload the core) - you have to write a routine
that finds documents matching the new keywords and reindex those documents.
Example:
Your keywordslist at time t1 contains two words:
keyword
codeword
You are indexing two documents:
doc1: {"content":"I am about a secret codeword."}
doc1: {"content":"Happy keyword and the gang."}
Your filter will mark "codeword" in doc1 and "keyword" in doc2 as words
to keep and remove everything else. Therefore their content for your
keepWordField contains only
doc1: {"indexedContent":"codeword"}
doc2: {"indexedContent":"keyword"}
However, if you add the word "gang" to your keywordlist AND reload your
SolrCore, doc2 will still only contain the term "keyword" until it gets
reindexed again.
