lucene - Removing unwanted items from solr autosuggester -


i trying implement auto suggest huge set of paragraphs indexed. want filter out unwanted words appearing in auto suggest. example words "and", "how", "when", etc needs avoided. how go it.

this configuration have done autosuggest in solrconfig.xml..

<requesthandler class="org.apache.solr.handler.component.searchhandler" name="/suggest">     <lst name="defaults">       <str name="spellcheck">true</str>       <str name="spellcheck.dictionary">suggest</str>       <str name="spellcheck.onlymorepopular">true</str>       <str name="spellcheck.count">5</str>       <str name="spellcheck.collate">true</str>     </lst>     <arr name="components">       <str>suggest</str>     </arr>   </requesthandler>   <searchcomponent class="solr.spellcheckcomponent" name="suggest"> <lst name="spellchecker">   <str name="name">suggest</str>   <str name="classname">org.apache.solr.spelling.suggest.suggester</str>   <str name="lookupimpl">org.apache.solr.spelling.suggest.tst.tstlookup</str>    <str name="field">keywords</str>    <float name="threshold">0.005</float>   <str name="buildoncommit">true</str>  </lst>

i recommend adding stopfilterfactory backing fieldtype definition keywords field in schema.xml file. if need words ("and", "how", "when") in keywords field other searching requirements, suggest creating custom field in schema.xml suggester , can use copyfield directive populate new field.

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 ...
