Which Analyzer is used for Solr-Query - solr

Question

I've added a field-type which uses the EdgeNgramFilter as analyzer to my schema.
{
"add-field-type" : {
"name":"text_edge_ngram",
"class":"solr.TextField",
"positionIncrementGap":"100",
"analyzer" : {
"tokenizer":{
"class":"solr.WhitespaceTokenizerFactory" },
"filters":[
{"class":"solr.LowerCaseFilterFactory"},
{ "class":"solr.EdgeNGramFilterFactory",
"minGramSize":"1",
"maxGramSize":"4"}
]
}
}
}
Further, I've assigned this type to one field:
{
"replace-field" : {
"name":"MyField",
"type":"text_edge_ngram",
"uninvertible":true,
"indexed":true,
"stored":true
}
}
I've reindexed my documents but now the following query does not return the expected results. Here comes an example:
.../select?q=aweso has no results
But, if I query that single field
.../select?q=MyField:aweso, I get 'awesome' as result.
It would be very nice, if anybody can explain what is going on or give me hint how to troubleshoot.

You need to set default search field in solrconfig.xml file under /query request handler or as IntParams
Default parameter values are specified in solrconfig.xml, or overridden by query-time values in the request.
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="df">MyField</str>
</lst>
</requestHandler>
I prefer not use the ConfigAPI to update the solr cofig setting and save default configuration directly in solrconfig.xml file.
Below configuration is for few request handlers you have defined:
<initParams path="/select,/get,standard">
<lst name="defaults">
<str name="df">term1 term2</str>
<str name="q.op">AND</str>
</lst>
</initParams>
This example SearchHandler declaration shows off usage of the
SearchHandler with many defaults declared.
Note that multiple instances of the same Request Handler
(SearchHandler) can be registered multiple times with different
names (and different init parameters)
