The documentation shows example about how store base64 documents into elasticsearch via ingest-attachment plugin. But after this I got that elasticsearch index contains parsed text and base64 field source. Why does it needed? Is there a way to remove base64 text field and keep only text after document was indexed not it content?

There's not option for that, but you can add a "remove" processor to your ingestion pipeline:
PUT _ingest/pipeline/attachment
{
"description": "Extract attachment information and remove the source encoded data",
"processors": [
{
"attachment": {
"field": "data",
"properties": [
"content",
"content_type",
"content_length"
]
}
},
{
"remove": {
"field": "data"
}
}
]
}
