Because you used solr.StandardTokenizerFactory which will tokenize terms at
some delimiters - such as the hyphens that surround your errant 404 case.
Try solr.WhitespaceTokenizerFactory or solr.KeywordTokenizerFactory.
And maybe rename your field type from "text_general_trim" to "text_exact"
since "general" implies a general text analyzer.
Test your field type changes on the Solr Admin Analysis page.

Hello,

i have looked at some of the threads up here related to this topic, but
still do not understand why the additional document is coming back.
here is my query:
http://someserver/somecore/select?qt=modelItemNoSearch&q=itemModelNoExactMatchStr:404&debugQuery=true&rows=50
here is my RH from the solrconfig.xml
<requestHandler name="modelItemNoSearch" class="solr.SearchHandler"
default="false">
<lst name="defaults">

<str name="sort">itemModelNoExactMatchStr asc</str>
</lst>
<lst name="invariants">

</requestHandler>
here is the field, copyField and text type from schema.xml
<field name="itemModelNoExactMatchStr" type="text_general_trim"
