Search for docs containing only a certain word in a specified field?

Hi, I wonder if there is a way to search for documents containing only a certain word in a specified field. For example, I would like to search for documents that contain only "the" in title field. Some titles just contain a single stop word, but I really need to find it. If the index is created

filter caching

I have a question about filter caching. I have a lot of QueryFilters that I use when searching that filter on a single field. Sometimes alone I use them by themselves, but mostly I use them in some combination using ChainedFilter. Does the caching take advantage of only the final filter that

Snowball and accents filter...?

Hi, all, Another quick request succinct for code examples, or an explanation of what we're doing wrong here. We've successfully gotten the Snowball Spanish stemmer working in our test harness. An example that works perfectly: texts that contain "civilización" or "civilizaciones" produce hits on s

Re: Index Update Strategies

Hi Andreas, There are two important parts here: 1) Index updates will impact search - just think about the disk IO. 2) You will further slow down the search speed by re-opening the index after detecting a change, as each new re-opening of IndexReader will have to read some of the index data. So
