Oh yes, final followup for the terminally curious; I also had to add
this little class in order to get analysis turned on for my programmatic
field:
class PathField extends TextField {
PathField (IndexSchema schema) {
setAnalyzer(new WhitespaceGapAnalyzer());
setQueryAnalyzer(new WhitespaceGapAnalyzer());
}
protected Field.Index getFieldIndex(SchemaField field, String
internalVal) {
return Field.Index.ANALYZED;
}
}

ok, never mind all is well - I had a mismatch between the
schema-declared field and my programmatic field, where I was
overzealous in using OMIT_TF_POSITIONS.

I'm creating a some Solr plugins that index and search documents in a

although I suppose they will have to register the plugins in
solrconfig.xml.
I tried making my UpdateProcessor "core aware" and creating
FieldTypes and SchemaFields in the inform(SolrCore) method. This was
a good start, but I'm running into some issues getting the types
properly initialized. One of my types, for example, derives from
TextField, but this seems to require an initialization pass in order
to get its properties set up properly. What I'm seeing is that my
field values aren't being tokenized, even though I specify TOKENIZED
when I create the SchemaField. I'm beginning to get the feeling I'm
doing something not-quite anticipated by the API designers.
My question is: is there a way to go about doing something like this
that isn't swimming upstream? Should I just give up and require
users to incorporate my schema in the xml config?
Here is a code snippet for anyone willing to dig in a little:
/** Called when each core is initialized; we ensure that lux
fields are configured. */
public void inform(SolrCore core) {
IndexSchema schema = core.getSchema();
Map<String,SchemaField> fields = schema.getFields();
if (fields.containsKey("lux_path")) {
return;
}
Map<String,FieldType> fieldTypes = schema.getFieldTypes();
FieldType luxTextWs = fieldTypes.get("lux_text_ws");
if (luxTextWs == null) {
luxTextWs = new TextField ();
luxTextWs.setAnalyzer(new WhitespaceGapAnalyzer());
luxTextWs.setQueryAnalyzer(new WhitespaceGapAnalyzer());
fieldTypes.put("lux_text_ws", luxTextWs);
}
fields.put("lux_path", new SchemaField ("lux_path",
luxTextWs, 0x233, "")); // 0x233 = INDEXED | TOKENIZED | OMIT_NORMS |
OMIT_TF_POSITIONS | MULTIVALUED
fields.put("lux_elt_name", new SchemaField ("lux_elt_name",
new StrField(), 0x231, ""));// INDEXED | OMIT_NORMS |
OMIT_TF_POSITIONS | MULTIVALUED
fields.put("lux_att_name", new SchemaField ("lux_att_name",
new StrField(), 0x231, ""));
// must call this after making changes to the field map:
schema.refreshAnalyzers();
}
