I'm reading this list eventually but it a very active list and useful,thks to all. But so often, when a developer search how to work with lucene finds normally the same code for same problems. I think it will be useful create something like Best practices with Lucene or something similar.
My question for example is a design question. Every time, you talk about a single index to use, in my case (a platform with user groups no related among themselves), i thinked the best option is use an index for every group, and when I need to search something over all i will use a Multisearcher instance (this action won't be frequently).My question is how can I do manage all indexation system. I thinked to create an IndexUpdater class which have a queue to recive all events over the platform, this queu it will be emptied every X minutes, and after this, Searcher will be updated. I won't your opinion how to manage all indexes, for example I can create a class (for exmaple EntityIndex) for every index which contains their respetives IndexSearcher,IndexReader,IndexWriter and have every EntityIndex in a hashmap. When it recived an element added in platform, gets their group id, and search in hashmap to get its EntityIndex and work over it. What do you think about this? Perhaps isn't a very good design and I want to know your advices. Thk for any reply, and I hope my question will be useful to others.
