> With Lucene based indexing the indexing process is single threaded. This hamper the indexing of binary content as on a multi processor system only single thread can be used to perform the indexing
> [~ianeboston] Suggested a possible approach [1] involving a 2 phase indexing
> # In first phase detect the nodes to be indexed and start the full text extraction of the binary content. Post extraction save the binary token stream back to the node as a hidden data. In this phase the node properties can still be indexed and a marker field would be added to indicate the fulltext index is still pending
> # Later in 2nd phase look for all such Lucene docs and then update them with the saved token stream
> This would allow the text extraction logic to be decouple from Lucene indexing logic
