Hello list,
I have recently been working on some JS (ajax solr) and when using Firebug I am
alerted to an error within the JS file as below.
It immediately breaks on line 12 stating that 'doc.text' is undefined! Here is
the code snippet.
10 AjaxSolr.theme.prototype.snippet = function (doc) {
11 var output = '';
12 if (doc.text.length > 300) {
13 output += doc.dateline + ' ' + doc.text.substring(0, 300);
14 output += '<span style="display:none;">' +
doc.text.substring(300);
15 output += '</span> <a href="#" class="more">more</a>';
16 }
17 else {
18 output += doc.dateline + ' ' + doc.text;
19 }
20 return output;
21 };
I have been advised that the problem might stem from my schema not defining a
text field, however as my implementation of Solr
is currently geared to index docs from a Nutch web crawl I am using the Nutch
schema. A snippet of the schema is below
<schema name="nutch" version="1.1">
<types>
...
<fieldType name="text" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
...
</types>
<fields>
...
<field name="content" type="text" stored="true" indexed="true"/>
</fields>
</schema>
Can someone confirm if I require to add something similar to the following
<fields>
...
<field name="text" type="text" stored="true" indexed="true"/>
</fields>
Then perform a fresh crawl and reindex so that the schema field is recognised
by the JS snippet?
Also (sorry I apologise) from my reading on the Solr schema, I became intrigued
in options for TextField... namely compressed
and compressThreshold. I understand that they are used hand in glove, however
can anyone please explain what benefits compression
adds and what integer value should be appropriate for the latter option.
Any help would be great
Thank you Lewis
