KinoSearch 0.20's RangeFilters are mostly implemented in C and are optimized for low cost over multiple searches.

The first time you search with a sort or range constraint on a particular field, there is a hit as a cache has to be loaded. The cache-loading can be significant with large indexes, but is only felt once if you are working in a persistent environment (mod_perl, FastCGI) and can keep the Searcher object around for reuse.

Once the cache is loaded, RangeFilter is extremely fast. There's an initial burst of disk activity as numerical bounds are found, then the rest is all fetching values from the cache and if (locus < lower_bound) C integer comparison stuff -- no matter how many docs match. There's hardly any overhead added above what's required to match the rest of the query.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
