Elastic search With MongoDB : Searching PDFs - mongodb

Question

I were trying to save my pdf file in Mongo Db's gridFS and then searching in that pdfs using elastic search. I performed following :
1) Mongo DB Side:
mongod --port 27017 --replSet rs0 --dbpath "D:\Mongo-DB\mongodb-win32-i386-2.0.7\data17"
mongod --port 27018 --replSet rs0 --dbpath "D:\Mongo-DB\mongodb-win32-i386-2.0.7\data18"
mongod --port 27019 --replSet rs0 --dbpath "D:\Mongo-DB\mongodb-win32-i386-2.0.7\data19"
mongo localhost:27017
rs.initiate()
rs.add("hostname:27018")
rs.add("hostname:27019")
mongofiles -hlocalhost:27017 --db testmongo --collection files --type application/pdf put D:\Sherlock-Holmes.pdf
2) Elastic Search Side (Installed Plugins : bigdesk/head/mapper-attachments/river-mongodb)
-> Using Elastic Search Head given following request from "Any request" tab
URL : http://localhost:9200/_river/mongodb/
_meta/PUT
{
"type": "mongodb",
"mongodb": {
"db": "testmongo",
"collection": "fs.files",
"gridfs": true,
"contentType": "",
"content": "base64 /path/filename | perl -pe 's/\n/\\n/g'"
},
"index": {
"name": "testmongo",
"type": "files",
"content_type": "application/pdf"
}
}
Now i am trying to access following URL :
http://localhost:9200/testmongo/files/508e82e21e43def09b5e1602?pretty=true
I got following response (Which i believe is as expected) :
{
"_index" : "testmongo",
"_type" : "files",
"_id" : "508e82e21e43def09b5e1602",
"_version" : 1,
"exists" : true, "_source" : {"_id":"508e82e21e43def09b5e1602","filename":"D:\\Sherlock-Holmes.pdf","chunkSize":262144,"uploadDate":"2012-10-29T13:21:38.969Z","md5":"025fa2046f9254d2aecb9e52ae851065","length":98272,"contentType":"application/pdf"}
}
But when i were trying to search on this pdf using following URL:
http://localhost:9200/testmongo/files/_search?q=Albers&pretty=true
Its giving me following result :
{
"took" : 0,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
Here its showing me no any hit but word "Albers" present in this pdf. Please help. Thanks in advance.

Answer 1

i think you have to specify the property to be searched
http://localhost:9200/testmongo/files/_search?q=<PROPERTYNAME>:Albers&pretty=true
or even for complex searches
$ curl -XPOST 'http://localhost:9200testmongo/files/_search?q' -d '{
<PROPERTYNAME> : "value",
<PROPERTYNAME> : {
<PROPERTYNAME> : "value",
<PROPERTYNAME> : "value"
}
}
'
but as far as i know you can only search for your defined properties after indexing your data.
