Error when trying to match file path
Hi all,
I am indexing the filepath with the below:
Document doc = new Document();
doc.add(Field.UnIndexed("path", f.getAbsolutePath()));
I then try to run the following after building the index:
this.query =
QueryParser.parse(file.getAbsolutePath(),"path",this.analyzer);
Hits hits = this.searcher.search(this.query);
It returns zero hits?!?
What am I doing wrong?
Any help would be appreciated.
Thanks,
Rob

Thanks for the reply, but I am already using a standard analyzer:
Analyzer analyzer =new StandardAnalyzer();
The path is being stored as a string so I do not know why I cannot find a
match when I used the path as a query? Do I need to phrase the query
differently?
QueryParser.parse(file.getAbsolutePath(),"path",this.analyzer);
Let me know.
Thanks,
Rob

Use filter instead of searching Re: Error when trying to match file path
Posted by Che Dong <ch...@hotmail.com>.
first indexing file path field with a untokened indexing field
Field("filePath", file.getAbsolutePath(), true, true, false)
second , construct a prefix filter for searcher.I wrote a StringFilter.java for match and prefix match which can download from:

RE: Error when trying to match file path
Posted by Rob Outar <ro...@ideorlando.org>.
I cannot get this to work for the life of me. I am using a Standard
analyzer now.
Question 1: What field type should the path be it be?
doc.add(Field.UnIndexed("path", f.getAbsolutePath())); where f is a
file object
Question 2: What should the query be to retieve that one file?
Term:
Term t = new Term("path",file.getAbsolutePath());
TermQuery tQ = new TermQuery(t);
System.out.println(tQ.toString("path"));
Hits hits = this.searcher.search(tQ);
System.out.println(hits.length() + " total matching documents");
or:
/* QueryParser parser = new QueryParser();
System.out.println(file.getAbsolutePath());
this.query = parser.parse(file.getAbsolutePath());
System.out.println(this.query.toString("path"));
Hits hits = this.searcher.search(this.query);
System.out.println(hits.length() + " total matching documents");
Document doc = hits.doc(0);
System.out.println("class = " + doc.get("classification"));*/
If I can get past this hurdle I will so be on my way.
Thanks,
Rob

The Analyzer is stripping your \ characters. Query Parser doesn't do
that...

Setting fields
Posted by Rob Outar <ro...@ideorlando.org>.
Hello,
Is there is way to set a field once it has been associated with a document?
For example if I have a field named filename, and the file is renamed I now
need to update the field filename with the new name of the file. I did not
see any setter methods on Field. The only solution that comes to mind is to
fetch the document based on it's URL, remove it from the index, then read it
with the new value.
Let me know,
Thanks,
Rob

RE: Error when trying to match file path
Posted by Rob Outar <ro...@ideorlando.org>.
I finally got it to work, but I do not understand the solution, instead of
storing the file path (F:\blah\blah\blah.xml), I stored the URL of file in
the field called path, I was then able to use a TermQuery(path, URL) to
retrieve that one document from the index.
Thanks,
Rob

RE: Error when trying to match file path
Posted by Rob Outar <ro...@ideorlando.org>.
Some more information, with the following:
this.query =
QueryParser.parse(file.getAbsolutePath(),"path",this.analyzer);
System.out.println(this.query.toString("path"));
I got:
F:"onesaf dev block b pair dev unittestdatafiles tools unitcomposer.xml"
So it looks like the Query Parser is stripping out all the "\", and doing
something with the F:\, would anyone happen to know why this is happening?
Do I need to use a different query to get the infromation I need?
Thanks,
Rob

Hi all,
I am indexing the filepath with the below:
Document doc = new Document();
doc.add(Field.UnIndexed("path", f.getAbsolutePath()));
I then try to run the following after building the index:
this.query =
QueryParser.parse(file.getAbsolutePath(),"path",this.analyzer);
Hits hits = this.searcher.search(this.query);
It returns zero hits?!?
What am I doing wrong?
Any help would be appreciated.

Re: Error when trying to match file path
Posted by Matthew King <ma...@gnik.com>.
Instead of UnIndexed, have you tried using a Keyword field?
From the javadoc:
Field.UnIndexed: Constructs a String-valued Field that is
not tokenized nor indexed, but is stored
in the index, for return with hits.
Field.Keyword: Constructs a String-valued Field that is
not tokenized, but is indexed and stored.
(note that I haven't tried this in code with file paths, so there may
still be analyzer tweaking necessary)
