Guide to Setting up GSearch 2.7 with Solr 4.2.0.
Stop Fedora
Download Solr 4.2.0 to /opt
Make a symbolic link to the solr directory such that /opt/solr => /opt/solr-4.2.0
ln -s /opt/solr-4.2.0 /opt/solr
Add the following XML file to $FEDORA_HOME/tomcat/conf/Catalina/localhost/solr.xml
<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="/opt/solr/dist/solr-4.2.0.war" debug="0" crossContext="true">
<Environment name="solr/home" type="java.lang.String" value="/usr/local/fedora/solr" override="true"/>
</Context>Copy over the default configuration files for "collection1" from /opt/solr/example/solr/collection1 to $FEDORA_HOME/solr/collection1
cp -r /opt/solr/example/solr/collection1 $FEDORA_HOME/solr/collection1
Goto to your solr conf directory.
cd $FEDORA_HOME/solr/collection1/conf
First backup the existing Schema, for reference incase any problems occur.
cp schema.xml schema.xml.bak
Use the provided schema file schema.xml
collection1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Plugin init failure for [schema.xml] fieldType "text": Plugin init failure for [schema.xml] analyzer/filter: Error loading class 'solr.EnglishPorterFilterFactory'
Changed the deprecated "EnglishPorterFilterFactory" to use "SnowballPorterFilterFactory".
<filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/>
Becomes
<filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt"/>
collection1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Unable to use updateLog: _version_field must exist in schema, using indexed="true" stored="true" and multiValued="false" (version is multiValued
Changed the version of the schema from 1.1 to version 1.5 which includes these changes:
1.2: omitTermFreqAndPositions attribute introduced, true by default
except for text fields.
1.3: removed optional field compress feature
1.4: autoGeneratePhraseQueries attribute introduced to drive QueryParser
behavior when a single string produces multiple tokens. Defaults
to off for version >= 1.4
1.5: omitNorms defaults to true for primitive field types
(int, float, boolean, string…)
Also Added the following field to the schema.
<field name="_version_" type="long" indexed="true" stored="true"/>
Goto to your solr conf directory.
cd $FEDORA_HOME/solr/collection1/conf
First backup the existing Schema, for reference incase any problems occur.
cp solrconfig.xml solrconfig.xml.bak
Tell solr that we want changes to be flushed and make changes available right away
sed -i 's|<openSearcher>false</openSearcher>|<openSearcher>true</openSearcher>|g' solrconfig.xml
Increase the size of the cache
sed -i 's|<queryResultWindowSize>20</queryResultWindowSize>|<queryResultWindowSize>50</queryResultWindowSize>|g' solrconfig.xml
Enable backwards compatibility
sed -i 's|<requestDispatcher handleSelect="false" >|<requestDispatcher handleSelect="true" >|g' solrconfig.xml
Update the /select requestHandler to tell solr about some of the fun things we want to index - makes islandora basic solr search work. The following commands will add some lines to your config file.
sed -i '782i<str name="fl">*</str>' solrconfig.xml
sed -i '783i<str name="q.alt">*:*</str>' solrconfig.xml
sed -i '784i<str name="qf">dc.title^5 dc.subject^3 dc.description^3 dc.creator^3 dc.contributor^3 dc.type^1 dc.relation^1 dc.publisher^1 mods_identifier_local_ms^3 ds.WARC_FILTER^1 text_nodes_HOCR_hlt^1 mods_subject_hierarchicalGeographic_region_ms^3 mods_identifier_hdl_mt^3 dc.identifier^3 PID^0.5 catch_all_fields_mt^0.1</str>' solrconfig.xml
Start Fedora
Place the fedoragsearch.war file in $FEDORA_HOME/tomcat/webapps
Navigate to $FEDORA_HOME/tomcat/webapps/fedoragsearch/FgsConfig.
cd $FEDORA_HOME/tomcat/webapps/fedoragsearch/FgsConfig
Backup the basic properties file, for reference in case any problems occur.
cp fgsconfig-basic.properties fgsconfig-basic.properties.bak
Modify the basic properties file as needed be sure that the following properties are set correctly: <path to fedora home> should be the absolute path to your $FEDORA_HOME directory typically /usr/local/fedora.
configDisplayName=configDemoOnSolr
local.FEDORA_HOME=<path to fedora home>
indexEngine=Solr
indexDir=${local.FEDORA_HOME}/solr/collection1/data/index
indexBase=http://localhost:8080/solr
indexingDocXslt=foxmlToSolr
Run the following commands:
ant generateIndexingXslt
ant -f fgsconfig-basic.xml
Ensure that you have added the DGI GSearch Extensions to GSearch, just follow the directions provided at the preceding link.
Go to the index directory of the GSearch
cd $FEDORA_HOME/tomcat/webapps/fedoragsearch/WEB-INF/classes/fgsconfigFinal/index/FgsIndex
Download foxmlToSolr.xslt and islandora_transforms to your current directory.
Uncomment the resolver in index.properties
fgsindex.uriResolver = dk.defxws.fedoragsearch.server.URIResolverImpl
If you keep Fedora or Tomcat in the non-default location, you will need to update each of the *.xslt files to reflect that as well.
Restart Fedora
/usr/local/fedora/tomcat/webapps/fedoragsearch/WEB-INF/classes/fgsconfigFinal/index/FgsIndex/foxmlToSolr.xslt was not present and it is the "default" solr xslt now in gsearch 2.7+.
Please read over sort out this issue see Install GSearch
cd $FEDORA_HOME/tomcat/webapps/fedoragsearch/FgsConfig
ant generateIndexingXslt
ant -f fgsconfig-basic.xml
Thu Oct 03 13:33:09 UTC 2013 IndexReader open error indexName=FgsIndex : ; nested exception is: org.apache.lucene.store.NoSuchDirectoryException: directory '/usr/local/fedora/solr/data/index' does not exist
Check the basic properties file as needed be sure that:
indexDir=${local.FEDORA_HOME}/solr/collection1/data/index
