Some issues with bad characters

http://128.101.146.59:8080/solr/select/?version=1.2&start=0&rows=10&indent=on&wt=standard&q=fullText:food&sort=modstitle desc&qt=mods

Should be:

http://128.101.146.59:8080/solr/select/?version=1.2&start=0&rows=10&indent=on&wt=standard&q=fullText:food++%26sort%3Dmodstitle%2Bdesc&qt=mods

Fields that Solr searches on should be single valued
Bill found out that fields that are being used for sort must be single values.  Our title field is not.  In the past SOLR would handle multivalued fields for sort.

The MODS schema

	<titleInfo>
 	 	<title>[dc.title]</title>
 	</titleInfo>
<titleInfo type="translated">
 	 	<title>[dc.title.alternative]</title>
 	</titleInfo>


The XSLT to make SOLR indices
Note the XSLT will not distinguish between different values of the type attribute, so there is more than version of title, it will no longer be single valued.

    <xsl:for-each select="foxml:datastream[@ID='MODS']/foxml:datastreamVersion[last()]/foxml:xmlContent//mods:titleInfo/mods:title">
         <xsl:if test="text() [normalize-space(.) ]"><!--don't bother with empty space-->
            <field>./WEB-INF/classes/config/index/GSearch_solr/demoFoxmlToSolr.xslt
               <xsl:attribute name="name">
                  <xsl:value-of select="concat('mods.', 'title')"/>
               </xsl:attribute>
               <xsl:value-of select="text()"/>
            </field>
         </xsl:if>
      </xsl:for-each>


Possible values for the type attribute of title element in MODS

From:  
http://www.loc.gov/standards/mods/v3/mods-userguide-elements.html  


		type - This attribute is applied when it is necessary to identify what type of title is recorded. 

        For the main title (MARC 21 field 245), no type is indicated. The following values may be used with the type attribute:

		abbreviated (equivalent to MARC 21 field 210)

		translated (equivalent to MARC 21 field 242, 246)

		alternative (equivalent to MARC 21 fields 246, 740)

		uniform (equivalent to MARC 21 fields 130, 240, 730)
