solr - Why does this code - adding wordnet synonyms to index - fail? -


i writing code part of customanalyzer:

public class customanalyzer extends analyzer {  synonymmap mysynonymmap = null;  customanalyzer() throws ioexception {     synonymmap.builder builder = new synonymmap.builder(true);      filereader fr = new filereader("/home/watsonuser/downloads/wordnetsynonyms.txt");     bufferedreader br = new bufferedreader(fr);     string line = "";      while ((line = br.readline()) != null) {       string[] synset = line.split(",");       for(string syn: synset)           builder.add(new charsref(synset[0]), new charsref(syn), true);     }      br.close();     fr.close();      try {         mysynonymmap = builder.build();     } catch (ioexception e) {         system.out.println("unable build synonymmap");         e.printstacktrace();     } }  public tokenstream tokenstream(string fieldname, reader reader) {     tokenstream result = new porterstemfilter(new synonymfilter(                                               (new stopfilter(true,new lowercasefilter                                                (new standardfilter(new standardtokenizer                                                  (version.lucene_36,reader)                                                 )                                                ),stopanalyzer.english_stop_words_set)), mysynonymmap, true)                                                );   } }

now, if use same customanalyzer part of querying, if enter query as

myfieldname: manager

it expands query synonyms manager.

but, want synonyms part of index , don't want query expanded synonyms.

so, when removed synonymfilter customanalyzer when querying index, query remains as

myfieldname: manager

but, fails retrieve documents have synonyms of manager.

how solve problem?

if not have synonym builder during query processing term match mapped during indexing. , not showing part here.

the best way troubleshoot @ admin/core/analysis screen (in solr 4+) , put text in. show happens text after each stage in indexing , queries run.

you don't need run reindexer. can define bunch of different types trying figure out , run analysis of sample sentences directly against types.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
