documents not auto indexing elasticsearch - indexing

Question

I have created an elasticsearch index. It searches everything correctly but when any new document is added it does not index it automatically. Everytime I have to restart the service for it to index the new document.
PUT /_river/mydocum1/_meta
{
"type": "fs",
"fs": {
"url": "\\\\file\\datum\\Depart\\Inet\\",
"update_rate": 3600,
"includes": [
"*.docx",
"*.xlsx",
"*.pdf",
"*.txt",
"*.doc",
"*.xls"
]
},
"index": {
"index": "test",
"type": "docum",
"bulk_size": 500
}
}
EDIT:
Here are the settings
{
"test": {
"settings": {
"index": {
"uuid": "9rofjAZySByrtehnjemkjudg",

}
},

],

},
"index_analyzer_4": {

},
"whitespace_analyzer": {
"type": "custom",
"filter": [
"lowercase",
"asciifolding"
],
"tokenizer": "whitespace"
}
}
}
}
}
Does anyone know how do I solve it?
