Lucene Empty Non-empty Fields

I did some experiments for finding empty fields, But i want to know whether there is any other better method. Have to reduce hard disk space. Method 1: Add "NULL String" in empty fields We can search with null string for empty column & non empty column Observations: - Index size will grow.

SpanNearQuery behaviour?

Hi, We use SpanNearQueries intensively for proximity searching. However, we are confused by two different ways to use them. Could anybody explain in details what we can expect for nested and flatten SpanNearQueries? We used to build nested SpanNearQueries. However, we found that using nested S

This is very cool! Lemmatization is an important tool for making search work better. Would you consider changing the licensing to the Apache 2.0 license? On 10/23/2013 08:17 AM, Michal Hlavac wrote: Hi, I rewrote lemmatizer project LemmaGen (http://lemmatise.ijs.si/) to java. Originally it's
