Greetings, I have an index where I import documents such as powerpoint, PDF, and so forth. One nice feature I added is that for each document, I store a thumbnail of the first page as an encoded String (uuencode) using a stored,not-indexed field. This thumbnail gets displayed when the user finds a document.
I am wondering if, as the size of the index grows to perhaps hundreds of thousands if not millions of documents, how efficient is this? Is it a good idea? These encoded strings could be several hundred bytes in size, and of course are completely unique for each file indexed, and provide no 'search' value. On the surface, it seems like there could be a better way to do this given the size, as well as the extra retrieval time for Lucene to pull these fields for found documents. Since I also have a unique hash for each document in the index, it would not be too difficult to set up a separate, independent NoSQL key/value store with the thumbnail images, such as MongoDB or similar, and then retrieve the thumbnails from that store instead of keeping them in the Lucene index. Does this seem like a better approach? Or is Lucene stored field retrieval efficient enough that there would be no benefit to doing this? Any other ideas?
