You can configure your schema.xml to
- Use copyfield to combine title, description, keywords into a single field, and then search on that field.
- Use EdgeNGramFilter filter to break the works into fragments so as to match the sql like behaviour.
e.g.
<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="25" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
<field name="all_fields" type="text" indexed="true" stored="false" multiValued="true"/>
<copyField source="title" dest="all_fields"/>
