Hmm... I was thinking about this, and if I am going to have to include
components of lucene anyway, why not just use MemoryIndex directly? This
shouldn't be a problem for me to do in my situation, so I am starting on
that code right now. This way I will create a MemoryIndex at the same
time I create a record. I will pass the record into a queue to be
written to Blur, and the MemoryIndex over to my analyzer engine which
checks the memoryindex. This will probably use a bit more memory because
I have to create two objects with the same info, but it should provide
me with the functionality I am looking for right now.
It would be nice though if an individual record could have a query
method so that you could query it directly though. Something like...
||Iface client = BlurClient.getClient("controller1:40010,controller2:40010");
|Query query = new Query();
query.setQuery("field1:value");
BlurQuery blurQuery = new BlurQuery();
blurQuery.setQuery(query);
Record newrec = new Record();|
||newrec.setRecordId("recordid1");
newrec.setFamily("fam0");|
newrec.addToColumns(new Column("field1", "value"));
||newrec.addToColumns(new Column("field2", "value"));|
if (newrec.query(blurQuery)) {
System.out.println("Match found");
} else {
System.out.println("No match found");
}
|List recordMutations = new ArrayList();
recordMutations.add(new RecordMutation(RecordMutationType.REPLACE_ENTIRE_RECORD, newrec));
RowMutation mutation = new RowMutation("table1", "rowid1", true,
RowMutationType.REPLACE_ROW, recordMutations, false);
mutation.setRecordMutations(recordMutations);
client.mutate(mutation);|
This would make it nice and easy to query the record and do things with
it on the fly... like for instance determining if you want to do the
mutation call or not.

Hmm... I've been trying to do this without any luck so far.
I cannot find where the objects Field, and Analyzer are declared... I
tried adding all of the blur libs as well as lucene analyzer common,
queries, and queryparser.
The Field class is a Lucene class, as well as the Analyzer class. The
FieldManager class is in the blur-query project, and the TableContext is in
the blur-core project.
Can you perhaps ellaborate a bit more on how to accomplish searching a
single record in memory.
I will see if I can come up with an example of something simple sometime
tomorrow.
Thanks,
Aaron

Are you talking the MemoryIndex in Lucene? If so, no Blur doesn't have
anything like that built in. However you could use the Analyzer and
FieldManager from Blur to help create a similar behavior.
TableContext context = TableContext.create(**TableDescriptor);
FieldManager fieldManager = context.getFieldManager();
List<Field> fields = fieldManager.getField(rowid,**record);
Analyzer analyzerForWriter = fieldManager.**getAnalyzerForIndex();
Analyzer analyzerForQuery = fieldManager.**getAnalyzerForQuery();

Hello,
I am wondering if it is possible to run a query against a single
record stored in memory? and if so can you give me an example? While
parsing and entering log entries into Blur, I would like to be able to
pass
that record over to a thread which analyzes the record with a query which
may trigger some kind of action. I used to be able to do this with
lucene... hmm... I was going to provide some example code, but I cannot
seem to find it.
