You could extend IndexWriter to AutoCommitIndexWriter and override flush()
to call super.flush() then commit() (or simply just commit()). I haven't
tested it but I think it should work.
However, make sure you understand the implications of commit() -- it's
heavier than just flush. Perhaps you can
flush is not commit.

in Chinese, there isn't word boundary between words. it writes like:
Iamok. you should tokenize it to I am ok
if you want to search *amo*, you should view I am ok as one token. In
Chinese, fuzzy search is not very useful. even use Standard Analyzer,
it's ok to use boolean query. because "Iamok" is

Thank, using Whitespace Analyzer works, but I don't understand why
StandardAnalyzer does not work if according with the ChineseAnalyzer
deprecation I should use StandardAnalyzer:
@deprecated Use {@link StandardAnalyzer} instead, which has the same
functionality.
Is very annoying.

thanks a lot
btw: docId is 0,1,2 but the delta is 0,1,2, not the 0,1,1.
The delta value is useless at this moment.
In which scene the delta value will be usefull?

it will not call finish after adding a document
reading the JavaDoc of FormatPostingsDocsConsumer
/** Called when w
lastDocID represent last document which contains this term.
because it will reuse this FormatPostingsDocsConsumer. so you need
clear all member variables in finish method

thanks
could you help me to solve another problem,
why lucene will reset lastDocID = 0 when finish add one doc?
in source code FormatPostingsDocsWriter.java
@Override
void finish() throws IOException {
long skipPointer = skipListWriter.writeSkip(out);
Maybe high frequency terms that are not evenly distributed throughout
the corpus would be a better definition. Discriminative terms. I'm
sure there is something in the machine learning literature about
unsupervised clustering that would help here. But I don't know what it
is :)

standard analyzer will segment each character into a token, you should use
whitespace analyzer or your own analyzer that can tokenize it as one token
for wildcard search

maybe you did not enable prefixquery feature.

I store the string "专项信息管理.doc" using the StandardAnalyzer and after that
search for "专项信*"
Cant he synchronously iterate over both fields postingLists and use one
priorityQueue that picks the docs that contain the query and have the best
order according to the second field.
It requires more work but this should be feasible.

Add imageid as a stored field, no need to index it unless you want to
be able to search by it.
Add the tags as an analyzed indexed field. no need to store unless you
want to read/display the values. StandardAnalyzer will work fine.
Then use QueryParser to build a query like "tags: car", execute
I think he wants 1, sort all matched docs by field A.
If lucene sorting doesn't work for you you can always sort the hits
yourself using whatever technique you want. Sorting large numbers of
docs is always going to be expensive.

Maybe you want high frequency terms. See contrib class

what do you want to do?
1. sort all matched docs by field A.
2. sort all matched docs by relevant score, selecting top 100 docs and
then sort by field A
