Solr : curl command for adding new multi-term synonyms

Question

We are trying to create/upload new synonyms to Solr as managed resources. We are facing some problems when we create multi-term synonyms like, for example, "United States of America" or "Spider Man". The Solr Documentation provides a curl command example for single-term synonyms but doesn't have a curl command example for multi-term.

We tried the following command and some variants:

1)

`curl -X POST -H "Content-type:application/json" ... --data-binary "["ARS","Argentinian Peso"]"`

2)

curl -X POST -H "Content-type:application/json" ... --data-binary '["ARS","Argentinian Peso"]'

3)

curl -X POST -H "Content-type:application/json" ... --data-binary [["ARS","Argentinian Peso"]]

For the three we got the following errors:

1)

{
  "responseHeader":{
    "status":500,
    "QTime":2},
  "error":{
    "msg":"Expected ',' or ']': char=(EOF),position=16 BEFORE='[ARS,Argentinian'",
    "trace":"org.noggit.JSONParser$ParseException: Expected ',' or ']': char=(EOF),position=16 BEFORE='[ARS,Argentinian'\n\tat org.noggit.JSONParser.err(JSONParser.java:356)...",
    "code":500}}

curl: (3) [globbing] unmatched close brace/bracket in column 5

2)

{
  "responseHeader": {
    "status": 500,
    "QTime": 2
  },
  "error": {
    "msg": "Bad Request",
    "trace": "Bad Request (400) - Unsupported update format java.lang.String\n\tat org.apache.solr.rest.ManagedResource.doPut(ManagedResource.java:410)...",
    "code": 500
  }
}

3)

{
  "responseHeader": {
    "status": 500,
    "QTime": 2
  },
  "error": {
    "msg": "Expected ',' or ']': char=P,position=18 BEFORE='[[ARS,Argentinian P' AFTER='eso]]'",
    "trace": "org.noggit.JSONParser$ParseException: Expected ',' or ']': char=P,position=18 BEFORE='[[ARS,Argentinian P' AFTER='eso]]'\n\tat org.noggit.JSONParser.err(JSONParser.java:356)...",
    "code": 500
  }
}

After we tried to create them from json file with success; we used the following curl command:

4)

curl -X POST -H "Content-type:application/json" ... --data-binary @synonyms_test.json

The synonyms_test.json has:

["USA","United States of America"]

After we tried to extend this 'workaround' because we need to create/upload thousands of synonyms to an existing collection. Then we decide to fill the json file with array of arrays (a valid json content):

[["aaa", "aaa1"],["bbb", "bbb1"]]

And the result was:

4)

{
  "responseHeader": {
    "status": 500,
    "QTime": 2
  },
  "error": {
    "msg": "java.util.ArrayList cannot be cast to java.lang.String",
    "trace": "java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String ...",
    "code": 500
  }
}

Do you have any idea how to solve this?

According to the documentation an example is the following

curl -X PUT -H 'Content-type:application/json' --data-binary '["funny", "entertaining", "whimiscal", "jocular"]' "http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english"

Which is the same as your number 2 example, except you are using POST not PUT. Try using PUT and see if that helps.

Also,

[["aaa", "aaa1"],["bbb", "bbb1"]]

is not a valid because you can only PUT an array of strings. To add multiple symmetric synonym groups, you will have to do one call for each array.

Hi Andrew! We tried both of your propositions and no one worked. Note that the command `curl -X POST -H "Content-type:application/json" ... --data-binary "["Euro","EUR"]"`is running well! – Daniel Moura Oct 25 '16 at 17:28
How about trying to use --data instead of --data-binary? – Andrew Daniel Oct 25 '16 at 19:49
Hi Andrew! With only --data (instead of --data-binary) we got the same error as 1) and 3). – Daniel Moura Oct 26 '16 at 08:12

Running below command will enable to add stopwords.

curl -X PUT -H 'Content-type:application/json' --data-binary \
 '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \
 "http://localhost:8983/solr/techproducts/schema/analysis/stopwords/english"
