Solr search Query with white spaces or without case sensitive and exact matching -


i implementing solr searching product not working in case. example:

productcode=030101 01

in schema.xml used 

<fieldtype name="string"  class="solr.strfield" sortmissinglast="true" omitnorms="true"/>   <field name="itemcode" type="string" indexed="true" stored="true" required="true"/>

if changed fieldtype i.e

<fieldtype name="text_ws" class="solr.textfield" positionincrementgap="100">       <analyzer type="index">         <tokenizer class="solr.whitespacetokenizerfactory"/>         <filter class="solr.reversedwildcardfilterfactory" withoriginal="true"                 maxposasterisk="2" maxposquestion="1" mintrailing="2" maxfractionasterisk="0"/>         <filter class="solr.lowercasefilterfactory"/>       </analyzer>       <analyzer type="query">         <tokenizer class="solr.whitespacetokenizerfactory"/>         <filter class="solr.lowercasefilterfactory"/>       </analyzer>     </fieldtype>   <field name="itemcode" type="text_ws" indexed="true" stored="true" required="true"/>

then searching productcode=030101 01 searching 

030101 02 030101 03 030101 04

now exact searching not working. have product code have lowercase , uppercase character creating problem in search.

thanks in advance time. ashu

if need lowercase & exact search, can remove 'whitespacetokenizerfactory' & 'reversedwildcardfilterfactory' during index & query fieldtype=text_ws?

also @ "solr.keywordtokenizerfactory"

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
