I'm running Elasticsearch 2.4 for about 250 documents.

Most of those documents have **_attachments_** , and hence I am using a field called 'field\_attachment\_base64' with type 'attachment' (mapper plugin). This field contains the full-text content of those attachments in base64 format.

With the default,

> **index.query.bool.max\_clause\_count = 1024**

, I hit the error - ' **Too many clauses**'.

When I increase the value to 10240, I don't see that error anymore. Are there better alternatives to the '`Too many clauses`' issue?

Here is the field with full-text content of attachments in base64 format -

> ```
> "field_attachment_base64" : {
> "type" : "attachment",
> "fields" : {
> "content" : {
> "type" : "string",
> "store" : true
> },
> "author" : {
> "type" : "string"
> },
> "title" : {
> "type" : "string"
> },
> "name" : {
> "type" : "string"
> },
> "date" : {
> "type" : "date",
> "format" : "strict_date_optional_time||epoch_millis"
> },
> "keywords" : {
> "type" : "string"
> },
> "content_type" : {
> "type" : "string"
> },
> "content_length" : {
> "type" : "integer"
> },
> "language" : {
> "type" : "string"
> }
> }
> },
