I am indexing a column in a database. I have chosen field type of text for
this column (this type was defined in the sample schema file which comes in
the Solr Example).
When I search for the word "impress" and top 3 results. I get these 3
documents
<str name="TEXT">bare desire pronounce villainy draught beasts blockish
impression acquit</str>
<str name="TEXT">bare impression villainy pronounce beasts desire blockish
draught acquit</str>
<str name="TEXT">beasts desire villainy pronounce bare acquit impression
draught blockish</str>
But here the TEXT doesn't really contain the word "impress" it contains the
word "impression"
Now the database does contain a few rows where the word "impress" is there,
but those rows do not come in top 3 results.
So my question is that why did the rows containing the word "impression" got
ranked higher than the rows containing the word "impress" when I searched
for "impress"?
My field type Text is defined as follows in the schema.
<fieldType name="text" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
-->
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
