the below way i did the search with lucene.net. this routine search multiple word against all index field called "Title", "Description", "Url", "Country" .
i need to know how can i give a condition like where country='UK' or country='US'
i want that multiple word should be search like below but i want to add one more clause that when country is UK. so please guide me what to add in my code.
if (!string.IsNullOrEmpty(multiWordPhrase))
{
string[] fieldList = { "Title", "Description", "Url" };
List<BooleanClause.Occur> occurs = new List<BooleanClause.Occur>();
foreach (string field in fieldList)
{
occurs.Add(BooleanClause.Occur.SHOULD);
}
searcher = new IndexSearcher(_directory, false);
Query qry = MultiFieldQueryParser.Parse(Version.LUCENE_29, multiWordPhrase, fieldList, occurs.ToArray(), new StandardAnalyzer(Version.LUCENE_29));
TopDocs topDocs = searcher.Search(qry, null, ((PageIndex + 1) * PageSize), Sort.RELEVANCE);
ScoreDoc[] scoreDocs = topDocs.ScoreDocs;
int resultsCount = topDocs.TotalHits;
list.HasData = resultsCount;
StartRecPos = (PageIndex * PageSize) + 1;
if (topDocs != null)
{
for (int i = (PageIndex * PageSize); i <= (((PageIndex + 1) * PageSize)-1) && i < topDocs.ScoreDocs.Length; i++)
{
Document doc = searcher.Doc(topDocs.ScoreDocs[i].doc);
oSr = new Result();
oSr.ID = doc.Get("ID");
oSr.Title = doc.Get("Title");
oSr.Description = doc.Get("Description");
//oSr.WordCount = AllExtension.WordCount(oSr.Description, WordExist(oSr.Title, multiWordPhrase));
string preview =
oSr.Description = BBAReman.AllExtension.HighlightKeywords(oSr.Description, multiWordPhrase); //sr.Description;
oSr.Url = doc.Get("Url");
TmpEndRecpos++;
list.Result.Add(oSr);
}
}
thanks
Look up BooleanQuery
if (!string.IsNullOrEmpty(multiWordPhrase))
{
BooleanQuery bq = new BooleanQuery();
string[] fieldList = { "Title", "Description", "Url" };
List<BooleanClause.Occur> occurs = new List<BooleanClause.Occur>();
foreach (string field in fieldList)
{
occurs.Add(BooleanClause.Occur.SHOULD);
}
Query qry = MultiFieldQueryParser.Parse(Version.LUCENE_29, multiWordPhrase, fieldList, occurs.ToArray(), new StandardAnalyzer(Version.LUCENE_29));
bq.Add(qry,BooleanClause.Occur.Must);
//this is the country query (modify the Country field name to whatever you have)
string country = "UK";
Query q2 = new QueryParser(Version.LUCENE_CURRENT, "Country", analyzer).parse(country);
bq.Add(q2,BooleanClause.Occur.Must);
searcher = new IndexSearcher(_directory, false);
TopDocs topDocs = searcher.Search(bq, null, ((PageIndex + 1) * PageSize), Sort.RELEVANCE);
ScoreDoc[] scoreDocs = topDocs.ScoreDocs;
int resultsCount = topDocs.TotalHits;
list.HasData = resultsCount;
StartRecPos = (PageIndex * PageSize) + 1;
if (topDocs != null)
{
//loop through your results

I'm trying to create a drop-down list on a grid. I was following the advice on this page. However, I'm not able to enter any string values for UserEnteredValue. The underlined error I'm getting:

I am working on implementing Search using Lucene.Net in my E Commerce site. I want to Sort by result depending on user selected criterion. It might be Name,Price,Discount,NewArrivals etc
My Code
var sortBy = new Lucene.Net.Search.Sort(new Lucene.Net.Search.SortField("Name", Lucene.Net.Search.SortField.STRING, true));
//var parser = new QueryParser(Lucene.Net.Util.Version.LUCENE_30, "Name", analyzer);
//Query searchQuery = parser.Parse(query);
//TopDocs hits = searcher.Search(searchQuery, int.MaxValue);
//Sort sort=new Sort
//TopDocs hits = searcher.Search(QueryMaker(query, searchfields, storeId), int.MaxValue);
TopFieldDocs hits = searcher.Search(QueryMaker(query, searchfields, storeId),null,int.MaxValue,sortBy);
int results = hits.TotalHits;
Product searchResult = null;
if (results < limit)
limit = results;
//if (limit == 0)
// limit = int.MaxValue;
for (int i = (pagenumber*limit) + 1; i <= ( ( pagenumber * limit ) + limit); i++)
{
try
{
Document doc = searcher.Doc(hits.ScoreDocs[i-1].Doc);
searchResult = new Product();
searchResult.Id = Convert.ToInt32(doc.Get("Id"));
searchResult.Name = doc.Get("Name");
searchResult.SeName = doc.Get("SeName");
searchResult.StoreId = Convert.ToInt32(doc.Get("StoreId"));
searchResults.Add(searchResult);
searchResult = null;
}
catch (Exception ae)
{
}
}
But this doesnt give me expected result and does not sort products using its Name

A few things wrong with this line:
UserTrafficReport_Create model =
await Task.WhenAll(
GetNewModel,
InitialCameras,
GetMonitoredWaysListAndPushViewData(mainRoadID, segmentID, cityid));
Task.WhenAll takes a collection of Task instances as an argument.
You're passing 2 delegates and a task. You probably meant to actually call the first two methods, so that they'll return a task?
Task.WhenAll returns a Task. Awaiting that task won't return anything, so you won't be able to assign anything to model.
Task<UserTrafficReport_Create> modelFactoryTask = GetNewModel(...);
await Task.WhenAll(
modelFactoryTask ,
InitialCameras(...),
GetMonitoredWaysListAndPushViewData(mainRoadID, segmentID, cityid));
UserTrafficReport_Create model = modelFactoryTask.Result;

However, now I need to be able to change the status and title of a case from C# given its incidentid.
Ive looked at the SDK docs and cannot find an example of this.
Anyone work with this before?
Thanks
Simply put, above is code to read an incident. Could I get an example of writing an incident field, Just one. Ex: How could I change the title of an incident.
You can call the Update method on the CrmService. Here is the SDK article.
Case c = new Case();
c.ID = id;
c.Title = title;
svc.Update(c);
To change the state of an entity you use the setstaterequest. If you want to do it to a dynamic entity there's a description in this blog
I am doing a project on search using Lucene.Net. We have created an index which contains 100 000 documents with 5 fields. But while searching I'm unable to track my correct record. Can anybody help me? Why is that so?
My code looks like this
List<int> ids = new List<int>();
List<Hits> hitList = new List<Hits>();
List<Document> results = new List<Document>();
int startPage = (pageIndex.Value - 1) * pageSize.Value;
string indexFileLocation = #"c:\\ResourceIndex\\"; //Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "ResourceIndex");
var fsDirectory = FSDirectory.Open(new DirectoryInfo(indexFileLocation));
Analyzer analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_29);
IndexReader indexReader = IndexReader.Open(fsDirectory, true);
Searcher indexSearch = new IndexSearcher(indexReader);
//ids.AddRange(this.SearchPredicates(indexSearch, startPage, pageSize, query));
/*Searching From the ResourceIndex*/
Query resourceQuery = MultiFieldQueryParser.Parse(Lucene.Net.Util.Version.LUCENE_29,
new string[] { productId.ToString(), languagelds, query },
new string[] { "productId", "resourceLanguageIds", "externalIdentifier" },
analyzer);
TermQuery descriptionQuery = new TermQuery(new Term("description", '"'+query+'"'));
//TermQuery identifierQuery = new TermQuery(new Term("externalIdentifier", query));
BooleanQuery filterQuery = new BooleanQuery();
filterQuery.Add(descriptionQuery, BooleanClause.Occur.MUST);
//filterQuery.Add(identifierQuery,BooleanClause.Occur.MUST_NOT);
Filter filter = new CachingWrapperFilter(new QueryWrapperFilter(filterQuery));
TopScoreDocCollector collector = TopScoreDocCollector.create(100, true);
//Hits resourceHit = indexSearch.Search(resourceQuery, filter);
indexSearch.Search(resourceQuery, filter, collector);
ScoreDoc[] hits = collector.TopDocs().scoreDocs;
//for (int i = startPage; i <= pageSize && i < resourceHit.Length(); i++)
//{
// ids.Add(Convert.ToInt32(resourceHit.Doc(i).GetField("id")));
//}
for (int i = 0; i < hits.Length; i++)
{
int docId = hits[i].doc;
float score = hits[i].score;
Lucene.Net.Documents.Document doc = indexSearch.Doc(docId);
string result = "Score: " + score.ToString() +
" Field: " + doc.Get("id");
}
You're calling Document.Get("id"), which returns the value of a stored field. It wont work without Field.Store.YES when indexing.
You could use the FieldCache if you've got the field indexed without analyzing (Field.Index.NOT_ANALYZED) or using the KeywordAnalyzer. (Meaning one term per field and document.)
You'll need to use the innermost reader for the FieldCache to work optimally. Here's a code paste from FieldCache with frequently updated index which uses the FieldCache in a proper way, reading an integer value from the id field.
// Demo values, use existing code somewhere here.
var directory = FSDirectory.Open(new DirectoryInfo("index"));
var reader = IndexReader.Open(directory, readOnly: true);
var documentId = 1337;
// Grab all subreaders.
var subReaders = new List<IndexReader>();
ReaderUtil.GatherSubReaders(subReaders, reader);
// Loop through all subreaders. While subReaderId is higher than the
// maximum document id in the subreader, go to next.
var subReaderId = documentId;
var subReader = subReaders.First(sub => {
if (sub.MaxDoc() < subReaderId) {
subReaderId -= sub.MaxDoc();
return false;
}
return true;
});
var values = FieldCache_Fields.DEFAULT.GetInts(subReader, "id");
var value = values[subReaderId];
