both way synonyms with ManagedSynonymFilterFactory

[Bjørn Hjelle]

Hi,

one-way managed synonyms seems to work fine, but I cannot make both-way
synonyms work.

Steps to reproduce with Solr 5.4.1:

1. create a core:
$ bin/solr create_core -c test -d server/solr/configsets/basic_configs

2. edit schema.xml so fieldType text_general looks like this:

    <fieldType name="text_general" class="solr.TextField"
positionIncrementGap="100">
      <analyzer>
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.ManagedSynonymFilterFactory" managed="english"
/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
    </fieldType>

3. reload the core:

$ curl -X GET "
http://localhost:8983/solr/admin/cores?action=RELOAD&core=test";

4. add synonyms, one one-way synonym, one two-way, reload the core again:

$ curl -X PUT -H 'Content-type:application/json' --data-binary
'{"mad":["angry","upset"]}' "
http://localhost:8983/solr/test/schema/analysis/synonyms/english";
$ curl -X PUT -H 'Content-type:application/json' --data-binary
'["mb","megabytes"]' "
http://localhost:8983/solr/test/schema/analysis/synonyms/english";
 $ curl -X GET "
http://localhost:8983/solr/admin/cores?action=RELOAD&core=test";

5. list the synonyms:
{
  "responseHeader":{
    "status":0,
    "QTime":0},
  "synonymMappings":{
    "initArgs":{"ignoreCase":false},
    "initializedOn":"2016-02-11T09:00:50.354Z",
    "managedMap":{
      "mad":["angry",
        "upset"],
      "mb":["megabytes"],
      "megabytes":["mb"]}}}


6. add two documents:

$ bin/post -c test -type 'application/json' -d '[{"id" : "1", "title_t" :
"10 megabytes makes me mad" },{"id" : "2", "title_t" : "100 mb should be
sufficient" }]'
$ bin/post -c test -type 'application/json' -d '[{"id" : "2", "title_t" :
"100 mb should be sufficient" }]'

7. search for the documents:

- all these return the first document, so one-way synonyms work:
$ curl -X GET "
http://localhost:8983/solr/test/select?q=title_t:angry&indent=true";
$ curl -X GET "
http://localhost:8983/solr/test/select?q=title_t:upset&indent=true";
$ curl -X GET "
http://localhost:8983/solr/test/select?q=title_t:mad&indent=true";

- this only returns the document with "mb":

$ curl -X GET "
http://localhost:8983/solr/test/select?q=title_t:mb&indent=true";

- this only returns the document with "megabytes"

$ curl -X GET "
http://localhost:8983/solr/test/select?q=title_t:megabytes&indent=true";


Any input on how to make this work would be appreciated.

Thanks,
Bjørn
