Hi Doron,
I m not sure I m implement your suggestion correctly.
The way I did is I have 2 separate methods controlling by the check box.
I used basic search method for the first time and that will look up the
index from the directory. After I got the result, I will check the checkbox
and that will lead to 2nd method which the reader again from the index
directory and searcher search based on the reader. Next, I m only implement
the codes that suggested by you. So, I m not sure I m doing the right thing
or not.
I have attached the work that I done on below:
public String search(String searchString) throws IOException,
Exception
{
StringBuffer buff = new StringBuffer();
String field = "";
try
{
reader = IndexReader.open(DsConstant.indexDir);
Searcher searcher = new IndexSearcher(reader);
Analyzer analyzer = new StandardAnalyzer();
QueryParser parser = new
QueryParser(DsConstant.idxFileContent,
analyzer);
//Query query = parser.parse(searchString);
String[] metaFields = field.split(":");
metaFields = new String[]{"contents", "companyId",
"ownerId",
"createdBy", "docName", "docDesc", "keywords", "docId", "docPropName"};
for(int i = 0; i < metaFields.length; i++)
{
buff.append(metaFields[i] + ":" + searchString);
if(i != (metaFields.length-1))
{
buff.append(" OR ");
}
}
Query query = parser.parse(buff.toString());
query = query.rewrite(reader);
System.out.println("query ::: " + query);
searchHits = searcher.search(query);
System.out.println("search hits is ::: "
+searchHits.length());
if(searchHits.length() > 0)
{
QueryScorer scorer = new QueryScorer(query);
Highlighter highlighter = new Highlighter(new
SimpleHTMLFormatter("<span
style='background-color:yellow; font-weight:bold;'>",
"</span>"),
scorer);
for(int i = 0; i < searchHits.length(); i++)
{
Document doc = searchHits.doc(i);
String text =
doc.get(DsConstant.idxFileContent);
TokenStream tokenstream =
analyzer.tokenStream(DsConstant.idxFileContent, new StringReader(text));
//buff.append("<p> '" +
DsConstant.userDir
buff.append("!");
buff.append("<p " +
searchHits.doc(i).get(DsConstant.idxPath) + " "
+
searchHits.doc(i).get("docName") + " <br>");
buff.append("score: " +
searchHits.score(i) + "<br>");
buff.append(highlighter.getBestFragments(tokenstream, text, 3, "...")+
"</p>");
}
//System.out.println("Folder path is ::: "
+DsConstant.folderPath);
searcher.close();
}
System.out.println("Found "+searchHits.length()+"
searchHits with query =
"+query);
}
catch(Exception e)
{
e.printStackTrace();
}
return buff.toString();
//return resultList;
}
public String refindSearchResult(String searchString1, String
searchString2) throws IOException, Exception
{
System.out.println("inside search util - refind search result");
IndexReader reader = null;
StringBuffer buff = new StringBuffer();
try
{
reader = IndexReader.open(DsConstant.indexDir);
Searcher searcher = new IndexSearcher(reader);
Analyzer analyzer = new StandardAnalyzer();
QueryParser parser = new
QueryParser(DsConstant.idxFileContent,
analyzer);
Query query1 = parser.parse(searchString1);
filter = new QueryFilter(query1);
Query query2 = parser.parse(searchString2);
searchHits = searcher.search(query2, filter);
System.out.println("search hits is ::: "
+searchHits.length());
if(searchHits.length() > 0)
{
QueryScorer scorer = new QueryScorer(query2);
Highlighter highlighter = new Highlighter(new
SimpleHTMLFormatter("<span
style='background-color:yellow; font-weight:bold;'>",
"</span>"),
scorer);
for(int i = 0; i < searchHits.length(); i++)
{
Document doc = searchHits.doc(i);
String text =
doc.get(DsConstant.idxFileContent);
TokenStream tokenstream =
analyzer.tokenStream(DsConstant.idxFileContent, new StringReader(text));
//buff.append("<p> '" +
DsConstant.userDir
buff.append("<p " +
searchHits.doc(i).get(DsConstant.idxPath) + " "
+
searchHits.doc(i).get("docName") + " <br>");
buff.append("score: " +
searchHits.score(i) + "<br>");
buff.append(highlighter.getBestFragments(tokenstream, text, 3, "...")+
"</p>");
buff.append("!").substring(i);
}
searcher.close();
}
System.out.println("Found "+searchHits.length()+"
searchHits with query =
"+query2);
}
catch(Exception e)
{
e.printStackTrace();
}
return buff.toString();
}
Please point out where I m done wrong and hopefully the right solution
that I can use.
Thank you.
regards,
Wooi Meng
