Hi,
We are developing a product in a agile manner and the current
implementation has a data of size just about a 800 megs in dev.
The memory allocated to solr on dev (Dual core Linux box) is 128-512.
My config
=========
<!-- autocommit pending docs if certain criteria are met
<autoCommit>
<maxDocs>10000</maxDocs>
<maxTime>1000</maxTime>
</autoCommit>
-->
<filterCache
class="solr.LRUCache"
size="512"
initialSize="512"
autowarmCount="256"/>
<queryResultCache
class="solr.LRUCache"
size="512"
initialSize="512"
autowarmCount="256"/>
<documentCache
class="solr.LRUCache"
size="512"
initialSize="512"
autowarmCount="0"/>
<enableLazyFieldLoading>true</enableLazyFieldLoading>
My Field
=======
<fieldType name="autocomplete" class="solr.TextField">
<analyzer type="index">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.PatternReplaceFilterFactory"
pattern="([^a-z0-9])" replacement="" replace="all" />
<filter class="solr.EdgeNGramFilterFactory"
maxGramSize="100" minGramSize="1" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.PatternReplaceFilterFactory"
pattern="([^a-z0-9])" replacement="" replace="all" />
<filter class="solr.PatternReplaceFilterFactory"
pattern="^(.{20})(.*)?" replacement="$1" replace="all" />
</analyzer>
</fieldType>
Problem
======
I execute a query that returns 24 rows of result. I pick 10 out of it. I have
no problem when I execute this.
But When I do sort it by a String field that is fetched from this result. I get
an OOM. I am able to execute several
other queries with no problem. Just having a sort asc clause added to the query
throws an OOM. Why is that.
What should I have ideally done. My config on QA is pretty similar to the dev
box and probably has more data than on dev.
It didnt throw any OOM during the integration test. The Autocomplete is a new
field we added recently.
Another point is that the indexing is done with a field of type string
<field name="XXX" type="string" indexed="true" stored="true"
termVectors="true"/>
and the autocomplete field is a copy field.
The sorting is done based on string field.
Please do lemme know what mistake am I doing?
Regards
Sundar
