![]() ![]() Now the very bad part is that neither of these values lend themselves to being good for searching or sorting. Worse yet, this conversion is dependent on the culture information used, so the same conversion done on a web server set in the United Kingdom (en-GB culture) returns: 13:35:40. If the default string conversion is used for this type, it returns a value of 1:35:40 PM. All field values are just treated as strings, which often can be problematic for. Documents can then be searched using a Domain Specific Language (DSL) querying language to evaluate for matching results.Ī common pitfall for Lucene field values is no underlying data type exists. Field values may be stored in the index for retrieval or sorting, and may also be analyzed (which is useful for free-form content searching). The documents in the index contain a list of name-value pairs called, fields. At its most basic level, Lucene is a collection of documents called an index. It has even been ported to run natively in the. Lucene is a widely used search tool, built in Java, allowing it to run on many different platforms. There are many different search engines to provide this functionality for a web site but in this article, we are looking at the free and open source Lucene. ![]() Common examples include news archive listings, which may go back decades, or finding content that is related to the current page being viewed. Many sections of a website may use search without the visitor even knowing.

Today, we look at Apache's free and open sourced Lucene search. Search is a critical component of a website that can go beyond a simple search box with results.
