Description

I'm using SearchClient.SuggestAsync, and when searching for special or unsafe characters in the query, the following exception occurs:

Azure.RequestFailedException: 'Failed to parse query string. See https://aka.ms/azure-search-full-query for supported syntax.
Status: 400 (Bad Request)
ErrorCode: InvalidRequestParameter

Content:

{
"error": {
"code": "InvalidRequestParameter",
"message": "Failed to parse query string. See https://aka.ms/azure-search-full-query for supported syntax.",
"details": [
{
"code": "InvalidSearchSyntax",
"message": "Failed to parse query string. See https://aka.ms/azure-search-full-query for supported syntax."
}
]
}
}

I have already followed the recommendation to escape special characters using "\", but the exception remains the same.

Thats how I call

var term = "###";
var filter = "tenantId eq 1";
var suggestion = await serviceClient
.SuggestAsync(term, searchConfiguration.SuggesterName,
new SuggestOptions { Filter = filter });

To reproduce, do a post to suggest with the body as shown below

Thank you in advance
