- an existing ranking servlet for solr was extended. It is now possible to set boost values for fields, boost functions and boost queries. - The ranking can have different instances, but currently only the first one is used - added an abstraction layer for fields which can be used for search and those fields can be edited in the solr ranking configruation - the ranking value from solr within the field score is used to combine remote search requests, which all are created using the same locally defined boost values - reduced the number of fields which are used for search (makes it faster) - replaced some text fields by string fields (makes indexing faster) - removed classes which had no use - made a large number of experiments for a better ranking and created a temporary setting which prefers hits inside titles - adjusted also the RWI-based ranking computation to 'prefer title' - made special cases like for portal search where no post-processing and post-ranking is wanted: this keeps the original ranking order as done by Solr - fixed many bugs with old settings for ranking

<h2>Solr Ranking Configuration</h2>
|
|
<p>These are ranking attributes for Solr. This ranking applies for internal and remote (P2P or shard) Solr access.</p>

<fieldset>
|
|
<legend>Boost Function</legend>
|
|
A Boost Function can combine numeric values from the result document to produce a number which is either added or multiplied with the other boost value from the query result.
|
|
To see all available fields, see the <a href="IndexSchema_p.html">YaCy Solr Schema</a> and look for numeric values (these are names with suffix '_i').
|
|
To find out which kind of operations are possible, see the <a href="http://wiki.apache.org/solr/FunctionQuery">Solr Function Query</a> documentation.
|
|
Example: to order by date, use "recip(ms(NOW,last_modified),3.16e-11,1,1)", to order by clickdepth, use "div(100,add(clickdepth_i,1))".

<legend>Boost Query</legend>
|
|
The Boost Query is attached to every query. Use this to statically boost specific content in the index.
|
|
Example: "fuzzy_signature_unique_b:true^100000.0f" means that documents, identified as 'double' are ranked very bad and appended to the end of all results (because the unique are ranked high).
|
|
To find appropriate fields for this query, see the <a href="IndexSchema_p.html">YaCy Solr Schema</a> and look for boolean values (with suffix '_b') or tags inside string fields (with suffix '_s' or '_sxt').
