NOTE: Facets are a really powerful feature. Given that we are indexing
asciidoc source
files, we could even use libraries like
https://github.com/asciidoctor/asciidoctorj[AsciidoctorJ]
to extract more metadata from our source files and store them as facets.

We leave this as an exercise for the reader.

+Let's use facets to store project names for each document.
+One facet capturing the project name information might be all we need,

+
+|===
+|Facet |Type |Description/Example
+
+|`projectHitCounts`
+|`IntAssociationFacetField`
+|Project reference hit counts, e.g.
+"Apache Lucene" has 2 hits in `groovy-lucene.adoc`
+
+|`projectFileCounts`
+|`FacetField`
+|Documents which reference a project, e.g.
+"Apache Spark" is referenced by
+`classifying-iris-flowers-with-deep.adoc`
+
+|`projectNameCounts`
+|`FacetField`
+|As above but hierarchical, e.g.
+["Apache", "Commons", "Math"] is reference by
+`fruity-eclipse-collections.adoc`
+|===

We'll use our regex to find project names and store the information in our
facets.
Lucene creates a special _taxonomy_ index for indexing facet information.
We'll also enable that.
