Stop word filter problem

Rajesh_Tarle · March 8, 2013, 8:37am

Hi,

I am using elastic search 0.20.5. when user stop word filter is not working.

my analyzer setting is in following link

gist.github.com

https://gist.github.com/rajesh07/16f4940de3afefba716e

AnalyzerMapping.json

 {  
  "index" : {
"analysis" : {
"analyzer" : {
 "mainindexanalyzer" : {
"type":"custom",
"tokenizer" : "whitespace",
"filter" : ["lowercase","asciifolding","mystopword"],
"char_filter" :["html_strip"]
 },

This file has been truncated. show original

and my stop word file is

I am creating index using following values
The oracle
The Rajesh
oracle company
The
oracle
Rajesh company
company
Rajesh

I got following indexes
it didn't remove stop word from values.
{id=4, CompanyName=The oracle}
{id=5, CompanyName=The Rajesh}
{id=1, CompanyName=oracle company}
{id=6, CompanyName=The}
{id=2, CompanyName=oracle}
{id=7, CompanyName=Rajesh company}
{id=3, CompanyName=company}
{id=8, CompanyName=Rajesh}

and when I search using "company" I got all record that contains "*company
*" like
{id=1, CompanyName=oracle company}
{id=7, CompanyName=Rajesh company}
{id=3, CompanyName=company}

i think it's wrong because company in stop word file.

I want the output like following
if i search for "company" then i must "get no record".
if i search for "oracle" the i must got
oracle
oralce(without "the" because "the" is also available in stopword file )
oralce(without "company" because "company" is also available in stopword
file )

and when i search for rajesh then search result is
Rajesh
Rajesh(without "the" because "the" is also available in stopword file )
Rajesh(without "company" because "company" is also available in stopword
file )

But i didn't get this result.
i think stopword is not working.
please help

Thanks
Rajesh

hey,

are you using the analyzers in your mapping? how do you create the index
ie. how does you mapping look like?

hi,
The mapping of analyzer look like

"primary" : {

"index_analyzer" : "mainindexanalyzer",*
"search_analyzer" : "mainsearchanalyzer"
}

and create index look like

{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"1"}}
{ "primary" :{"id":1,"CompanyName":"oracle company"}}
{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"2"}}
{ "primary" :{"id":2,"CompanyName":"oracle"}}
{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"3"}}
{ "primary" :{"id":3,"CompanyName":"company"}}
{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"4"}}
{ "primary" :{"id":4,"CompanyName":"The oracle"}}
{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"5"}}
{ "primary" :{"id":5,"CompanyName":"The Rajesh"}}
{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"6"}}
{ "primary" :{"id":6,"CompanyName":"The"}}
{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"7"}}
{ "primary" :{"id":7,"CompanyName":"Rajesh company"}}
{ "index" : { "_index" :"idx", "_type" :"primary", "_id" :"8"}}
{ "primary" :{"id":8,"CompanyName":"Rajesh"}}

Thanks

I am using rabbitmq river for creating an index.

The sequence of defining analyzer first define analyzer
mapping(index/search) on index then use rabbitmq river to insert the data
on index.

1.CreateIndexResponse createindexresponseactionGet =
client.admin().indices().create(new
CreateIndexRequest(indexName).settings(analyzerSettingSources)).actionGet();

client.prepareIndex("_river", "river",
"_meta").setSource(jsonBuilder().startObject().field("type",
"rabbitmq").field("rabbitmq", rabbitMqRiversettings).field("index",
riverIndexSetting).endObject()).execute().actionGet();

please look on it and provide any suggestion.

Thanks

The stopword filter comes after the lowercase filter in your analyzer,
therefore the stopwords should all be lowercased in the file or set
ignore_case to true.
