Dear Chris, Hi, Thank you for your response. Actually I implemented a small code for the purpose of extracting article keywords out of Lucene index on commit, optimize or calling the specific query. I did implement that using search component. I know that the searchComponent is not for the purpose of updating index, but it was suggested in Solr mailing list at the first place and it seems it is the most possible solution according to Solr extension points. Anyway for more information about why I chose searchComponent at the first place please take a look at this <https://mail-archives.apache.org/mod_mbox/lucene-solr-user/201503.mbox/browser> link.
Best regards.
