Re: How do I represent a group of customer key/value pairs
I do not understand exactly the data modeling problem.
PathHierarchyTokenizerFactory may be what you're looking for. You
might have to combine this with a charfilter or some token filters to
get exactly what you want. Maybe have two fields, one which only saves
the leaf words and the other that only saves the tree words?

Re: How do I represent a group of customer key/value pairs
Thanks Lance. It looks like it's worth investigating. I've already
started down the path of using a bean with "@Field(map_*)" on my
HashMap setter. This defect tipped me off on this functionality:
https://issues.apache.org/jira/browse/SOLR-1357
This technique provides me with a mechanism to store the HashMap data,
but flattens the structure. I'll play with the ideas provided on
"http://wiki.apache.org/solr/HierarchicalFaceting";. If anyone has
some sample code (java + schema.xml) they can point me too that does
"Hierarchical Faceting" I would very much appreciate it.

Re: How do I represent a group of customer key/value pairs
There are more advanced ways to embed hierarchy in records. This describes them:

Thanks for the prompt reply Jack. Could you point me towards any code
examples of that technique?

Re: How do I represent a group of customer key/value pairs
The general rule in Solr is simple: denormalize your data.
If you have some maps (or tables) and a set of keys (columns) for each map
(table), define fields with names like _, such as
"map1_name", "map2_name", "map1_field1", "map2_field1". Solr has dynamic
fields, so you can define "_*" to have a desired type - if all the
keys have the same type.

Subject: How do I represent a group of customer key/value pairs
I've just started to learn Solr and I have a question about modeling data
in the schema.xml.
I'm using SolrJ to interact with my Solr server. It's easy for me to store
key/value paris where the key is known. For example, if I have:
title="Some book title"
author="The authors name"
I can represent that data in the schema.xml file like this:
I also have data that is stored as a Java HashMap, where the keys are
unknown:
Map map = new HashMap();
map.put("some unknown key", "some unknown data");
map.put("another unknown key", "more unknown data");
I would prefer to store that data in Solr without losing its hierarchy.
For example:
Then I could search for "some unknown key", and receive "some unknown data".
Is this possible in Solr? What is the best way to store this kind of data?
