Subject Understand Solr Query Execution
Date Sun, 04 May 2014 20:20:30 GMT
How will a query like below will get executed, In which order

I understand that when this query is executed fields mentioned in fieldList
will be returned. What I don't understand is how the "samplestring1" and
"samplestring2" will get searched with the query fields specified

I think I will be able to understand how the search happens if this can be
illustrated in SQL ( Just to understand what happens behind the scene)

Following is the query. Please have a look at it and let me know how this
works internally.
query=samplestring1 AND samplestring2
defType: edismax
queryFields: Exact_Field1^1.0 Exact_Field2^0.9 Field1^0.8 Field2^0.7
fieldList: Column1, Column2
resultRows: 10
startRow: 0

P.S samplestring1 AND samplestring2  are some test strings in the query

Sample of Schema for fields

<fieldType name="sampletype1" class="solr.TextField"
positionIncrementGap="100"><analyzer type="index"><tokenizer
class="solr.KeywordTokenizerFactory"/><filter
class="solr.LowerCaseFilterFactory"/><filter class="solr.NGramFilterFactory"
minGramSize="5" maxGramSize="10"/></analyzer><analyzer
type="query"><tokenizer class="solr.KeywordTokenizerFactory"/><filter
class="solr.LowerCaseFilterFactory"/></analyzer></fieldType>

<fieldtype name="sampletype2" class="solr.TextField" sortMissingLast="true"
omitNorms="true"><analyzer><tokenizer
class="solr.KeywordTokenizerFactory"/><filter
class="solr.LowerCaseFilterFactory"/></analyzer></fieldtype>

<field name="Field1" compressed="true" type="sampletype1"
multiValued="false" indexed="true" stored="true" required="true"
omitNorms="true"/>

<field name="Field2" compressed="true" type="sampletype1"
multiValued="false" indexed="true" stored="true" required="true"
omitNorms="true"/>

<field name="Exact_Field1" omitPositions="true" termVectors="false"
omitTermFreqAndPositions="true" compressed="true" type="sampletype2"
multiValued="false" indexed="true" stored="true" required="true"
omitNorms="true"/>

<field name="Exact_Field2" omitPositions="true" termVectors="false"
omitTermFreqAndPositions="true" compressed="true" type="sampletype2"
multiValued="false" indexed="true" stored="true" required="false"
omitNorms="true"/>

<copyField source="Field1" dest="Exact_Field1"/>
<copyField source="Field2" dest="Exact_Field2"/>
