I would like search text contains of words like **I'm** or **you're** and so on using Elasticsearch. It probably should be used synonym token filter. At index time I used below code:

```
'analyzer' => [
	'default' => [
		'type' => 'custom',
		'tokenizer' => 'standard',
		'filter' => ['standard', 'lowercase', 'Snowball_filter', 'synonym_filter']
	],
	'search_analyzer' => [
		'type' => 'custom',
		'tokenizer' => 'standard',
		'filter' => ['standard', 'lowercase', 'Snowball_filter', 'synonym_filter']
	]
],
'filter' => [
	'Snowball_filter' => [
		'type' => 'snowball',
		'language' => 'English'
	],
	"synonym_filter" => [
		"type" => "synonym",
		"synonyms" => ["I'm,I am => I'm ","you're , you are => you're"]
	]
]

```

Now, suppose I have four documents:

1- I am a student.  
2- I'm a student.  
3- there are students.  
4- Am I a student?

And I use query like below:

```
[
	"match_phrase" => [
		"body" => [
			"query" => $q,
			"analyzer" => 'search_analyzer',
			"boost" => 100.0
		]
	]
],
[
	"match_phrase" => [
		"body" => [
			"query" => $q,
			"analyzer" => 'search_analyzer',
			"slop" => "1",
			"boost" => 45.0
		]
	]
],
[
	"match" => [
		"body" => [
			"query" => $q,
			"analyzer" => 'search_analyzer',
			"operator" => "and",
			"boost" => 10.0
		]
	]
],
[
	"match" => [
		"body" => [
			"query" => $q,
			"analyzer" => 'search_analyzer',
			"operator" => "or",
			"fuzziness" => "1",
			"boost" => 1.0
		]
	]
]

```

When I search _I'm a student_ the result is:  
1- I am a student.  
2- I'm a student.  
3- there are students.  
4- am i a student?

While I expected the result in order:  
1- I'm a student.  
2- I am a student.  
3- am i a student?  
4- there are students.

Please help me to understand this type of search with contraction words to get better relevance. Thanks in advance.
