The following example will search for the images which have value = pdx regardless of the key.

https://idr-testing.openmicroscopy.org/searchengine//api/v1/resources/image/search/?value=pdx&operator=equals

It supports search by value only in addition it can be used as a part of complex queries, e.g mixing search by key and value with search by value.

For example, the following query will search for the images which have cell type = m481, and value = pdx regardless of whether the key is for the latter

{
   "query_details":{
      "and_filters":[
         {
            "name":"Cell Type",
            "value":"m481",
            "operator":"equals",
            "resource":"image"
         },
         {
            "value":"pdx",
            "operator":"equals",
            "resource":"image"
         }
      ],
      "or_filters":[
         
      ]
   }
}

curl command can be used for the previous query:

curl -X POST "https://idr-testing.openmicroscopy.org/searchengine//api/v1/resources/submitquery/" -H "accept: application/json" -H "Content-Type: application/json" -d "{\"query_details\": {\"and_filters\": [{\"name\": \"Cell Type\",\"value\": \"m481\",\"operator\": \"equals\",\"resource\": \"image\"},{\"value\": \"pdx\",\"operator\": \"equals\",\"resource\": \"image\"}],\"or_filters\": []}}"
