Hi.
I've been using Lucene.Net since the 1.4 version, recently moved to
the 2.0004 build and seems to work rather well.
After a rebuild of the code a search for para* yields 453 hits, 9 of which
are excluded by some later logic matching URIs from the index to guarantee
uniqueness of results. If I then immediately after fire another search for
para* it yields exactly 1 hit. This also happens if I've done another search
against the index and then try para* . At first I was sure it was my own
exclusion code that was removing too much, but after lots of logging and
debugging it turns out the Lucene Hits object only contains 1 hit after the
crucial IndexSearcher.search(query, ....) call. I'm at a loss as to why this
happens. Can't seem to recreate the issue with any other search. But I can
recreate the issue when moving the code from one server to another.
Here's the relevant code (queryField gets set from a different method
depending on which index we're searching against):
StandardAnalyzer analyzer = new StandardAnalyzer();
QueryParser qp = new QueryParser(queryField, analyzer);
Query query;
int totalHits = 0;//Total hits
StringBuilder sb = new StringBuilder();
int docHits = 0;
Boolean scoreFound = false
try
{
//If there's a space in our search we want to enclose it
with ""
if (search.Contains(" "))
{
sb.Append("\"");
sb.Append(search);
sb.Append("\"");
}
else
{
sb.Append(search);
}
if (log.IsDebugEnabled)
{
log.Debug("Search: " + sb.ToString()); //Returns
para*
}
query = qp.Parse(sb.ToString());
if (log.IsDebugEnabled)
{
log.Debug("Search made against index: " +
query.ToString()); //Returns contents:para*
}
string weightToSetBoost = tRow.weight;
double weightOfToken = double.Parse(weightToSetBoost,
allowDecimal);
query.SetBoost((float) weightOfToken);
Hits hits = isearch.Search(query); //isearch is the
IndexSearcher
if (log.IsDebugEnabled)
{
log.Debug("COUNTING HITS: " + hits.Length());
//Returns 454 the first time, then 1 any other time for the query para*
}
TreatHits(searchResult, maxHits, hits, originalToken,
indexShort);
//The TreatHits() method is where I thought the error was occurring,
//but since the hit count is 1 as early as the Lucene Hits object, I'm
stumped
I've also tried this with the 003 build and the same happens then.
Let me know if any more information/code is needed.
Anyone run into something similar and willing to share their
experience/solution?
Christopher
