I am trying to create an index with the following settings (I don't have a Hebrew plugin and I am trying to create a simple Hebrew analyzer):

{
	"analysis" : {		
		"filter" : {			
			"hebrew_common_grams_index" : {
				"type" : "common_grams",
				"common_words" : ["אבל", "או", "אולי", "אותה", "אותו", "אותי", "אותך", "אותם", "אותן", "אותנו", "אז", "אחר", "אחרות", "אחרי", "אחרים", "אחרת", "אי", "איזה", "איך", "אין", "איפה", "איתה", "איתו", "איתי", "איתך", "איתכם", "איתכן", "איתם", "איתן", "איתנו", "אך", "אל", "אלה", "אלו", "אם", "אנחנו", "אני", "אם", "אף", "אצל", "אשר", "את", "אתה", "אתכם", "אתכן", "אתם", "אתן", "באמצע", "באמצעות", "בגלל", "בין", "בלי", "במידה", "ברם", "בשביל", "בתוך", "גם", "דרך", "הוא", "היא", "היה", "היכן", "היתה", "היתי", "הייתי", "הם", "הן", "הנה", "הרי", "ואילו", "ואת", "זאת", "זה", "יהיה", "יוכל", "יוכלו", "יותר", "יכול", "יכולה", "יכולות", "יכולים", "יכלו", "יש", "כאן", "כאשר", "כולם", "כולן", "כזה", "כי", "כיצד", "כך", "ככה", "כל", "כלל", "כמו", "כן", "כפי", "כאשר", "לא", "לאו", "לאן", "לבין", "לה", "להיות", "להם", "להן", "לו", "לי", "לכם", "לכן", "למה", "למטה", "למעלה", "למרות", "לנו", "לעבר", "להיכן", "לפיכך", "לפני", "מאד", "מאחורי", "מאין", "מאיפה", "מבלי", "מבעד", "מדוע", "מדי", "מה", "מהיכן", "מול", "מחוץ", "מי", "מכאן", "מכיוון", "מלבד", "מן", "מניין", "מנין", "מסוגל", "מעט", "מעטים", "מעל", "מצד", "מתחת", "מתי", "נגד", "נו", "עד", "על", "עלי", "עליה", "עליהם", "עליהן", "עליו", "עליך", "עליכם", "עלינו", "עם", "עצמה", "עצמו", "עצמי", "עצמם", "עצמן", "עצמנו", "פה", "רק", "שוב", "שוב", "של", "שלה", "שלהם", "שלהן", "שלו", "שלי", "שלך", "שלכם", "שלכן", "שלנו", "שם", "תהיה", "תחת"],

		},
		"analyzer" : {			
			"hebrew_index" : {

	}
}

but when I run it I get the following error:

What's wrong with this setting and what is the org.elasticsearch.index.analysis.hebrew.HebrewAnalyzerProvider class that cannot be found?

Thanks!

The above post has been submitted a month ago - can please someone from Elastic answer it?

I think you need to try something like:

"default" : {
      "type" : "custom",
      "tokenizer" : "whitespace",
      "char_filter" : ["html_strip"],
      "filter" : ["lowercase", "english_stemmer", "hebrew_common_grams_query"]
}

Same for default_search but it does not really make sense to set it here as it's already defined by default.

Thank you, David, this works!
I was assuming that I could name a new analyzer and use its name in defining "default" but I guess that was a mistake.
