Hello, I am currently evaluating Lucene to see if it would be appropriate to replace my company's current search software. So far everything has been looking great, however there is one requirement that I am not too certain about.
What we need to do is to be able to store a bit mask specifying various filter flags for a document in the index and then search this field by specifying another bit mask with desired filters, returning documents that have any of the specified flags set. In other words, we are doing a bitwise OR on the stored filter bit mask and the specified filter bit mask and if it is non-zero, we want to return the document. Before I started toying around with various options myself, I wanted to see if any of you good folks in the Lucene community had some suggestions for an efficient way to implement this. We currently need to index ~8,000,000 documents. We have several filter flag fields, the most important of which currently has 7 possible flags with any combination of the flags being valid. The number of flags is expected to increase rather rapidly in the near future. My preemptive thanks for your suggestions, Lawrence Taylor Senior Software Engineer Employon Message was edited by: ltaylor.employon
