Solr email address search returns 0 results -


i trying allow partial or full email search in solr 4.0.

here test cases:

  • flast@company.com
  • flast

i tried this. not getting exact result first case whole email provided , not getting result second result (which happens unique value), means solr isn't looking email field.

here truncated schema. must missing obvious, not seeing it.

<schema name="search" version="1.5"> <types>     <fieldtype name="long" class="solr.trielongfield" precisionstep="0" positionincrementgap="0"/>      <fieldtype name="text_email" class="solr.textfield" sortmissinglast="true" omitnorms="true" autogeneratephrasequeries="true">       <analyzer type="index">         <tokenizer class="solr.standardtokenizerfactory" />         <filter class="solr.lowercasefilterfactory" />         <filter class="solr.worddelimiterfilterfactory" />       </analyzer>       <analyzer type="query">         <tokenizer class="solr.standardtokenizerfactory" />         <filter class="solr.lowercasefilterfactory" />         <filter class="solr.worddelimiterfilterfactory" />       </analyzer>     </fieldtype> </types>  <fields>     .     .     .     <field name="email" type="text_email" indexed="true"  stored="true"/>     .     .     . </fields>

use worddelimiterfilterfactory below. 

<filter class="solr.worddelimiterfilterfactory"                 generatewordparts="1"                 generatenumberparts="0"                 catenatewords="0"                 catenatenumbers="0"                 catenateall="0"                 preserveoriginal="1"                 />

generatewordparts="1" generate parts of words:

preserveoriginal="1" causes original token indexed without modifications.

the final type should :

<analyzer type="index">         <tokenizer class="solr.standardtokenizerfactory" />         <filter class="solr.worddelimiterfilterfactory"                 generatewordparts="1"                 generatenumberparts="0"                 catenatewords="0"                 catenatenumbers="0"                 catenateall="0"                 preserveoriginal="1"                 />         <filter class="solr.lowercasefilterfactory" />       </analyzer>       <analyzer type="query">         <tokenizer class="solr.standardtokenizerfactory" />         <filter class="solr.worddelimiterfilterfactory"                 generatewordparts="1"                 generatenumberparts="0"                 catenatewords="0"                 catenatenumbers="0"                 catenateall="0"                 preserveoriginal="1"                 />         <filter class="solr.lowercasefilterfactory" />       </analyzer>

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
