<h2>Index Sources & Targets</h2>
|
|
<p>
|
|
YaCy supports multiple index storage locations.
|
|
As an internal indexing database a deep-embedded multi-core Solr is used and it is possible to attach also a remote Solr.
|
|
</p>
|
|
|
|
<form id="config" action="IndexFederated_p.html" method="post" enctype="multipart/form-data" accept-charset="UTF-8">
|

<input type="hidden" name="transactionToken" value="#[transactionToken]#" />

<fieldset>

|
<legend>Solr Search Index</legend>
|
|
Solr stores the main search index. It is the home of two cores, the default 'collection1' core for documents and the 'webgraph' core for a web structure graph. Detailed information about the used Solr fields can be edited in the <a href="IndexSchema_p.html">Schema Editor</a>.

<dd>
|
|
This will write the YaCy-embedded Solr index which stored within the YaCy DATA directory.<br/>
|
|
The Solr native search interface is accessible at<br/>
|
|
<a href="solr/select?q=*:*&start=0&rows=3&core=collection1">/solr/select?q=*:*&start=0&rows=3&core=collection1</a>
|
|
for the default search index (core: collection1) and at<br/>
|
|
<a href="solr/select?q=*:*&start=0&rows=3&core=webgraph">/solr/select?q=*:*&start=0&rows=3&core=webgraph</a> for the webgraph core.<br/>
|
|
If you switch off this index, a remote Solr must be activated.</dd>
|
|
|
|
<dt>Use remote Solr server(s) <input type="checkbox" name="solr.indexing.solrremote" id="solr_indexing_solrremote" #(solr.indexing.solrremote.checked)#:: checked="checked"#(/solr.indexing.solrremote.checked)# onclick="if(!document.getElementById('config').solr_indexing_solrremote.checked) {document.getElementById('config').core_service_fulltext.checked = true;}"/></dt>
|
|
<dd>It's easy to <a href="http://www.yacy-websearch.net/wiki/index.php/Dev:Solr" target="_blank">attach an external Solr to YaCy</a>.
|
|
This external Solr can be used instead the internal Solr. It can also be used additionally to the internal Solr, then both Solr indexes are mirrored.

You can set one or more Solr targets here which are accessed as a shard. For several targets, list them using a ',' (comma) as separator.
|
|
The set of remote targets are used as shard of a complete index. The host part of the url is used as key for a hash function which selects one of the shards (one of your remote servers).
|
|
When a search request is made, all servers are accessed synchronously and the result is combined.</dd>

Web Structure Index
|
|
</legend>
|
|
The web structure index is used for host browsing (to discover the internal file/folder structure), ranking (counting the number of references) and file search (there are about fourty times more links from loaded pages as in documents of the main search index).

The 'RWI' (Reverse Word Index) is necessary for index transmission in distributed mode. For portal or intranet mode this must be switched off.
