Hi
I have tried to upgrade lucene from 4.x to 5.0 recently.I found out from
documentation that FieldCache is removed from lucene 5, and I should use
DocValues fields for sorting.
I upgraded my sources, and everything works fine except spatial sorting by
distance.
When I looked into PointVectorStra
tor();
fieldsReader.visitDocument(i, visitor);
visitor.getDocument();
}
}
I was wondering if there is better way of doing this and if there are plans
to make access to the faster document loading through some API. Should I
try to come up with a patch for this?
Thanks!
Anton
Reindexing. If I want to add new fields or change existing fields in the
index I need to go through all documents of the index.

Hi,
I have performance issues with CachingWrapperQuery with lucene 5.2 and
dont know how to solve it.
Prehistory:
I have search with different parameters, where some parameters are used
more frequently then others. For these params I used filters(and cached
them), and my search looked li
t any caching 115ms.
Huh, I think that's all. I would appreciate any advice.

You can always throw an exception in the collector to stop the collection
process.

I guess I could go through the code myself to understand this but may be

I've the following problem:
I've a big number of documents indexed.
Suppose that the search query contains 20 terms. It is necessary to find
all documents which contains at least 5 terms from search query.
Is it possible to implement? If yes, what problems may arise during the
solving of thi
Is it possible to add records into lucene index using following
algorithm:
1) create Document object
2) add 5 fields into Document (id, name, field1, field2, field3). All
fields are stored, indexed and tokenized
3) check if the document with current id and name was added before
4) if yes
Ir is IndexReader.
termIdent is Term
int freq = ir.docFreq(termIdent);
if (freq > 1) {
TermDocs termDocs = ir.termDocs(termIdent);
int[] docsArr = new int[freq];
int[] freqArr = new int[freq];
int number = termDocs.read(docsArr,freqArr);
System.out.println(number)
I have a problem.
There is an index, which contains about 6,000,000 records (15,000,000
will be soon) the size is 4GB. Index is optimized and consists of only
one segment. This index stores the products. Each product has brand,
price and about 10 more additional fields. I want to not just find
so
Is it possible to make search among results of previous search?
For example: I made search:
Searcher searcher =...
Query query = ...
Hits hits =
hits = Searcher.search(query);
After it I want to not make a new search, I want to make search among found
results
Now I create new search for get number of results. For example:
IndexSearcher is = ...
Query q = ...
numberOfResults = Is.search(q).length();
Can I accelerate this example ? And how ?
What faster RangeQuery or RangeFilter ?
1.644 sec.
Second way return results fot 3.088 sec.
Why first way faster then second?
Can I accelerate it? And how? Can you offer any ways for get number of
results?

2) How do I display the sentence the hit is in? and color the hit.
3) How do I display the sentence before and after the sentence the hit
