I am currently facing challenges in optimizing the speed of my Zend Lucene index, which contains approximately 1 million documents. Searching through it sometimes takes up to 0.4 seconds, which is not acceptable. My goal is to have search results returned within a maximum of 0.1 second.
The documentation lacks information on performance issues of the engine, except for mentioning that it is well-scalable. The only solution provided is the use of the optimize() method, which I find insufficient. Therefore, I have two specific inquiries:
Does the order of fields added to each row (document) impact performance?
Are there any additional parameters or settings that could potentially improve its speed? This could include indexing parameters or adjustments to server settings such as increasing memory allocation, etc.
