Hello there! Since I've just begun with lucene, some concepts are kinda new for me :). One of the is the whole indexing process. Well, AFAIK, indexing should happen in a batch process right, to maximize the time spent on this operation. One issue tough, is that our client wants "instants search results", I mean, after something is added, the next search should have it available. Well, it's almost impossible to convince him (and I believe you guys know how this works) that indexing should not happen online (maybe I'm just wrong here as well).
Well, my question is, when I have a reasonable amount of indexed data, how expensive is to add a new document? Does it re-builds the entire index? I believe we'll have a small amount of data (when compare to things I've seen lucene is capable of), probably 50k of html docs, 10k of pdf, and 5--6 million rows of database information. With that scenario, an online index (plus optimize) would be a good idea? Best regards -- "In a world without fences and walls, who needs Gates and Windows?"
