Re: Query regarding Solr-2242 patch for getting distinct facet counts.
In solr 1.4.1, for getting distinct facet terms count across shards,
The piece of code added for getting count of distinct facet terms across
distributed process is as followed:
Class: facetcomponent.java
Function: -- finishStage(ResponseBuilder rb)
for (DistribFieldFacet dff : fi.facets.values()) {
//just after this line of code
else { // TODO: log error or throw exception?
counts = dff.getLexSorted();
int namedistint = 0;
namedistint=rb.req.getParams().getFieldInt(dff.getKey().toString(),FacetParams.FACET_NAMEDISTINCT,0);
if (namedistint == 0)
facet_fields.add(dff.getKey(), fieldCounts);
if (namedistint == 1)
facet_fields.add(numfacetTerms, counts.length);
if (namedistint == 2) {
NamedList resCount = new NamedList();
resCount.add(numfacetTerms, counts.length);
resCount.add(counts, fieldCounts);
facet_fields.add(dff.getKey(), resCount);
}
Is this flow correct ? I have worked with few test cases and it has worked
fine. but i want to know if there are any bugs that can creep in here? (My
concern is this piece of code should not effect the rest of logic)
*Code flow with comments for reference:*
Function : -- finishStage(ResponseBuilder rb)
//in this for loop ,
for (DistribFieldFacet dff : fi.facets.values()) {
//just after this line of code
else { // TODO: log error or throw exception?
counts = dff.getLexSorted();
int namedistint = 0; //default
//get the value of facet.numterms from the input query
namedistint=rb.req.getParams().getFieldInt(dff.getKey().toString(),FacetParams.FACET_NAMEDISTINCT,0);
// based on the value for facet.numterms==0 or 1 or 2 , if conditions
//Get only facet field counts
if (namedistint == 0)
{
facet_fields.add(dff.getKey(), fieldCounts);
}
//get only distinct facet term count
if (namedistint == 1)
{
facet_fields.add(numfacetTerms, counts.length);
}
//get facet field count and distinct term count.
if (namedistint == 2) {
NamedList resCount = new NamedList();
resCount.add(numfacetTerms, counts.length);
resCount.add(counts, fieldCounts);
facet_fields.add(dff.getKey(), resCount);
}

for f.2.facet.numFacetTerms=1 parameter it will give the distinct count
result
for f.2.facet.numFacetTerms=2 parameter it will give counts as well as
results for facets.
But this is working only across single index not distributed process. The
conditions you have added in simple facet.java- if namedistinct count ==int
( 0, 1 and 2 condtions).. Should it be added in distributed process
function to enable it work across shards?

No such issues . Successfully integrated with 1.4.1 and it works across single index. for f.2.facet.numFacetTerms=1 parameter it will give the distinct count result for f.2.facet.numFacetTerms=2 parameter it will give counts as well as results for facets.
