lucene.net - Lucene Duplicated results / spaces in text search -

-

i’m using lucene 2.9.4.1 , works fine if search exists once in same line. per instance, if lucene find same string i’m looking in same line, have duplicated (or more) results.

i’m using following booleanquery:  booleanquery.add(new termquery(new term(propertyinfo.name, textsearch)), booleanclause.occur.should);

the second issue searching spaces “hello world”: never works.

can advise me or me these 2 malfunctioning features, please?

thank in advance, best regards,

well, found answer solved both of issues =)

i using this:

booleanquery booleanquery = new booleanquery(); propertyinfo[] propertyinfos = typeof(t).getproperties(); foreach (propertyinfo propertyinfo in propertyinfos) {     booleanquery.add(new termquery(new term(propertyinfo.name, textsearch)), booleanclause.occur.should); }

and use this:

var booleanquery = new booleanquery(); textsearch = queryparser.escape(textsearch.trim().tolower());  string[] properties = typeof(t).getproperties().select(x => x.name).toarray();  analyzer analyzer = new standardanalyzer(global::lucene.net.util.version.lucene_29); multifieldqueryparser titleparser = new multifieldqueryparser(lucene.net.util.version.lucene_29, properties, analyzer); query titlequery = titleparser.parse(textsearch);  booleanquery.add(titlequery, booleanclause.occur.should);

it seems analyzer , multifieldqueryparser solution problems: no more duplicated results, can search spaces , … performance raised (faster results) =)

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
