Hi,
I have individual index files for Audio, Image and PDF files. We build common
meta fields for them. When I search for a string, I want the search defaults to
return mixed search results from these 3 different index based on relevancy.
But I also wants to know hit count for each individual index type. For example,
I want to get:
Mixed together total hit count: 105, with the first 10 HitItem.
Total hit in Audio: 73
Total hit in Image: 17
Total hit in PDF: 15
Right now, I'm doing the following way:
1. Gets one Searchable instance for Audio, one for Image, and one for PDF index;
2. construct ParallelMultiSearcher s with above 3 Searchable as parameters;
call its search to get total hit count and first 10 hit items;
3. Call Audio searchable to get total hit count in Audio;
4. Call Image searchable to get total hit count for Image;
5. Call PDF searchable to get total hit count for Image.
So, Lucene will need do 6 search operations for these 3 index. Definitely, the
performance will be an issue.
Any experts can give me some advice? Thanks!
Tony
