Hi folks,
I have a nice javascript (I will be happy to provide) for
autosuggestion of search terms.
For the search on my magnolia system I want to use this script to
display search terms, that actually deliver a hit from the index.
Therefore I need a method that lists all the search terms that
actually provide a hit.
I couldn't quite figure out how this can be done and would be very
thankful for any hints.
I am using Magnolia 2.1
Thx, Christoph

Hello folks,
I will answer my own question, which was "how to retrieve all search
terms that deliver a hit in magnolia search". From looking at the JCR
API you cannot list the search terms that actually deliver a hit.
However, in the jackrabbit-implementation of the JCR, internally a
lucene index is used. The API of lucene does have this functionality.
So, what I do is manually open the index and list all tokens for the
indexed field "title" and "fulltext".
I am not sure whether this is a smart/elegant way to achieve this. I
would have liked to discuss this with some of the users/developers out
there, but unfortunately nobody bothered replying to my question.
Here is a code snippet for whom it may concern:
private List getSearchTokens() {
String fileString =
request.getSession().getServletContext().getRealPath("/")
+"repositories/website/workspaces/default/index";
ArrayList result = new ArrayList();
try{
ArrayList result = new ArrayList();
File[] fileArray = new File(fileString).listFiles();
for (int i = 0; i < fileArray.length; i++) {
File f = fileArray[i];
if (f.isDirectory()){
IndexReader idxR = IndexReader.open(f);
TermEnum enum = idxR.terms();
while(enum.next()){
Term t = enum.term();
if(t.field().equals(TERM_FIELD_TITLE)
|| t.field().equals(TERM_FIELD_TEXT)){
if(!result.contains(t.text())
&& t.text().length()>2 //only words
between 2
&& t.text().length()<11 // and 10
characters
&& t.text().indexOf("@")<0) //no
email adresses
result.add(t.text());
}
}
}
}
}
catch(Exception ex){
ex.printStackTrace();
}
return result;
}
Cheers, Christoph
