I'm using AnalyzerWrapper to do per-field analyzer to do special indexing:
PerFieldAnalyzerWrapper analyzer = new PerFieldAnalyzerWrapper(..);
// PerFieldAnalyzerWrapper is subclass of Lucene's AnalyzerWrapper
IndexWriterConfig iwc = new IndexWriterConfig(analyzer);
However, i found that later w
hi i have filed a issue to lucene-core:

i just write a test case, and find that BooelanQuery with MUST filter mode
is ok, but PhraseQuery fails

I use SmartChineseAnalyzer to do the indexing, and add a document with a
TextField whose value is a long sentence, when anaylized, will get 18 terms.
& then i use the same value to construct a PhraseQuery, setting slop to 2,
and adding the 18 terms concequently...

In my understanding from reading the oniline documentation, LatLonPoint is
used for BKD indexing, and LatLonDocValuesField is used for Sort argument's
input.
But does it means if a POI has a GeoPoint type "location" field, then i
must add the same location value to the 2 fields which makes me conf
I'm doing a POI(Point-of-interest) search using lucene, each POI has a
"location" which is a GeoPoint/LonLat type. I need do a keyword-range
search but the query result POIs need to sort by distance to a starting
point.
This "distance", in fact, is a dynamic computed property which cannot be
used
Hi everybody,
I want to implement an auto-keyword-correction mode custom query: suppose a
scenario where user inputs a keyword query A, but due to typo or other
reasons, A should be B, A is not a valid term in lucene's index which B is.
(I'm not considering NLP in high-dimensional semantice space
ne should be able to a high-perf
Top-N query if SortField can support dynamically-generated ranking
scores... not only the native indexed numeric/String fields)

Assume i first use keyword search to get a DocIDSet from inverted index,
then i want to sort these docIds by some numeric field, like a
`updateTime`, does Lucene do this without need of loading the Document
objects but only with an sorted index on `updateTime`? Which i call it

I have a document `category` field, which is a "|,;" separator separated
string, in indexing phase, i do manually split the value into atomic terms
and index as StringField, & i also add a same name StoredField which
contains original value form:
*List terms = analyzer.analysis((String)fieldVa
Directory indexDataDir = FSDirectory.open(Paths.get("index_data"));
Analyzer analyzer = MyLuceneAnalyzerFactory.newInstance();
IndexWriterConfig iwc = new IndexWriterConfig(analyzer);
iwc.setOpenMode(OpenMode.CREATE);
iwc.setRAMBufferSizeMB(256.0);

Background: i need to implement a document indexing and search for
POIs(point of interest) under LBS scene. A POI has name, address, and
location(LatLonPoint), and i want to combine a text query with a
geo-spatial 2d range filter.
The problem is, when i first build a native in-memory index which u
17 matches
