Question

I am using apachesolr module in drupal
I have created a custom facet field subject but in drupal facet block, the sentence is breaking in multiple line/result
for example the subject Analytical chemistry would be
<int name="analyt">1</int>
<int name="chemistri">1</int>

I have tables journal, subject, subject_journal and article
My data config file has entity

<entity name="subject" pk="id"
                    query="select s.id, s.title from subject s
                            join subject_journal sj on sj.subject_id = s.id
                            join article a on a.journal_id = sj.journal_id
                            where sj.journal_id = '${article.journal_id}' 
                            group by s.id, s.title">
                    <field column="id" name="subject_id" /> 
                    <field column="title" name="subject" />                         
        </entity>

Please help
Thanks

Answer 1

you seem to be performing analysis on your facet field.

General facet field detail –

Faceting fields are often specified to serve two purposes, human-readable text and drill-down query value, they are frequently indexed differently from fields used for searching and sorting:

They are often not tokenized into separate words
They are often not mapped into lower case
Human-readable punctuation is often not removed (other than double-quotes)
There is often no need to store them, since stored values would look much like indexed values and the faceting mechanism is used for value retrieval.

you should maintain a seperate copy for the facet field and perform no analysis on it, and use that as the facet field.

<field name="subject" type="text_general" indexed="true" stored="true" multiValued="true"/>
<!-- Maintain different facet field -->
<field name="subject_facet" type="string" indexed="true" stored="true" multiValued="true"/>

<!-- copy field -->
<copyField source="subject" dest="subject_facet"/>
