Ahmet,

I modified the schema as follows: (Added more fields for faceting)


<field name=3D"title" type=3D"text" indexed=3D"true" stored=3D"true"
omitNorms=3D"true" />

<field name=3D"author" type=3D"text" indexed=3D"true" stored=3D"true"

<field name=3D"shortdesc" type=3D"text" indexed=3D"true" stored=3D"true" />

<field name=3D"subtitle" type=3D"text" indexed=3D"true" stored=3D"true"
omitNorms=3D"true"/>

<field name=3D"price" type=3D"float" indexed=3D"true" stored=3D"true"/>

<field name=3D"author_facet" type=3D"string" indexed=3D"true" stored=3D"tru=

<field name=3D"category_facet" type=3D"string" indexed=3D"true" stored=3D"t=
rue"
multiValued=3D"true" omitNorms=3D"true"/>

<field name=3D"award_facet" type=3D"string" indexed=3D"true" stored=3D"true=

multiValued=3D"true" omitNorms=3D"true"/>

<field name=3D"age_facet" type=3D"string" indexed=3D"true" stored=3D"true"

"
omitNorms=3D"true"/>

<field name=3D"price_facet" type=3D"string" indexed=3D"true" stored=3D"true=
"
omitNorms=3D"true"/>

Also added Copy Fields as below:


<copyField source=3D"author" dest=3D"author_facet"/>

<copyField source=3D"pubyear" dest=3D"pubyear_facet"/>

<copyField source=3D"format" dest=3D"format_facet"/>

<copyField source=3D"series" dest=3D"series_facet"/>

<copyField source=3D"season" dest=3D"season_facet"/>

<copyField source=3D"imprint" dest=3D"imprint_facet"/>

<copyField source=3D"category" dest=3D"category_facet"/>

<copyField source=3D"award" dest=3D"award_facet"/>

<copyField source=3D"age" dest=3D"age_facet"/>

<copyField source=3D"reading" dest=3D"reading_facet"/>

<copyField source=3D"grade" dest=3D"grade_facet"/>

<copyField source=3D"price" dest=3D"price_facet"/>
With the above changes I am not getting any facet data as a result.

Why is that the facet data not returning and what mistake I did with the
schema?

Thanks,
Solr User
