RE: Arabic words search in solr

Hi Aman Deep Singh,

Thanks for your update... I will update the status after complete the
testing.

I need one more help from your end,can you check below scenario:

we are getting the results while using AND operator in between the words. 

Below is the example: 

Scenario 1:

{ 
  "responseHeader": { 
"status": 0, 
"QTime": 1, 
"params": { 
  "indent": "true", 
  "q": "bizNameAr:(مسقط AND الاتصال)", 
  "_": "1501998206658", 
  "wt": "json" 
} 
  }, 
  "response": { 
"numFound": 44, 
"start": 0, 
"docs": [ 
  { 
"id": "56367", 
"bizNameAr": "بنك مسقط - مركز الاتصال", 
"_version_": 1574621133647380500 
  }, 
  { 
"id": "27224", 
"bizNameAr": "بلدية مسقط -  - بلدية مسقط - مركز الاتصالات", 
"_version_": 1574621132817956900 
  }, 
  { 
"id": "148922", 
"bizNameAr": "بنك مسقط - ميثاق - مركز الاتصال", 
"_version_": 1574621136335929300 
  }, 
  { 
"id": "23695", 
"bizNameAr": "قوة السلطان الخاصة - مركز الإتصالات  - مسقط", 
"_version_": 1574621132683739100 
  }, 
  { 
"id": "34992", 
"bizNameAr": "طوارئ الكهرباء - محافظة مسقط - مركز الاتصال", 
"_version_": 1574621133116801000 
  }, 
  { 
"id": "96500", 
"bizNameAr": "شركة مسقط لتوزيع الكهرباء( ام اي دي سي)  - مركز
الاتصال", 
"_version_": 1574621134575370200 
  }, 
  { 
"id": "23966", 
"bizNameAr": "ديوان البلاط السلطاني - القصر - مسقط - المديرية العامة
للاتصالات ونظم المعلومات -  - المديرية العامة للاتصالات ونظم المعلومات -
البدالة", 
"_version_": 1574621132692127700 
  }, 
  { 
"id": "24005", 
"bizNameAr": "ديوان البلاط السلطاني - القصر - مسقط - المديرية العامة
للاتصالات ونظم المعلومات -  - مدير عام الاتصالات ونظم المعلومات -", 
"_version_": 1574621132694225000 
  }, 
  { 
"id": "24026", 
"bizNameAr": "ديوان البلاط السلطاني - القصر - مسقط - المديرية العامة
للاتصالات ونظم المعلومات -  - مساعد مدير عام الاتصالات ونظم المعلومات -", 
"_version_": 1574621132694225000 
  }, 
  { 
"id": "24096", 
"bizNameAr": "ديوان البلاط السلطاني - القصر - مسقط - المديرية العامة
للاتصالات ونظم المعلومات -  - مدير دائرة الاتصالات والصيانة -", 
"_version_": 1574621132697370600 
  } 
] 
  } 
} 


Scenario 2:. 

{ 
  "responseHeader": { 
"status": 0, 
"QTime": 1, 
"params": { 
  "indent": "true", 
  "q": "bizNameAr:(مسقط AND الات)", 
  "_": "1501998438821", 
  "wt": "json" 
} 
  }, 
  "response": { 
"numFound": 0, 
"start": 0, 
"docs": [] 
  } 
} 

We are expecting same results in the scenario 2 as well where am not typing
the second word fully as in scenario’s 2 input. 


Below are the inputs used in both scenarios: 

Scenario 1:
First word: مسقط 
Second word: الاتصال 

Scenario 2:
First word: مسقط 
Second word: الات 

However, in our current production environment both of the above scenarios
are working fine, but we have an issue of “Hamza” character where we are not
getting results unless typing “Hamza” if it’s there. 

{ 
  "responseHeader": { 
"status": 0, 
"QTime": 9, 
"params": { 
  "fl": "businessNmBl", 
  "indent": "true", 
  "q": "businessNmBl:شرطة إزكي", 
  "_": "1501997897849", 
  "wt": "json" 
} 
  }, 
  "response": { 
"numFound": 1, 
"start": 0, 
"docs": [ 
  { 
"businessNmBl": "شرطة عمان السلطانية - قيادة شرطة محافظة الداخلية  - 
- مركز شرطة إزكي" 
  } 
] 
  } 
} 

Thanks,

RE: Arabic words search in solr

[mohanmca01]

Hi Phil Scadden,

 Thank you for your reply,

we tried your suggested solution by removing hyphen while indexing, but it
was getting wrong results. i was searching for "شرطة ازكي" and it was
showing me the result that am looking for, plus irrelevant result which
either have the first or second word that i have typed while searching.

First word: شرطة 
Second Word: ازكي

results that we are getting:


{
  "responseHeader": {
"status": 0,
"QTime": 3,
"params": {
  "indent": "true",
  "q": "bizNameAr:(شرطة ازكي)",
  "_": "1501678260335",
  "wt": "json"
}
  },
  "response": {
"numFound": 444,
"start": 0,
"docs": [
  {
"id": "28107",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة الداخلية  -  -
مركز شرطة إزكي",
"_version_": 1574621132849414100
  },
  {
"id": "13937",
"bizNameAr": "مؤسسةا الازكي للتجارة والمقاولات",

"bizNameAr": "بنك ظفار - فرع ازكي",
"_version_": 1574621133920010200
  }
]
  }
}

Actually  we expecting the below results only since it has both the words
that we typed while searching:

  {
"id": "28107",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة الداخلية  -  -
مركز شرطة إزكي",
"_version_": 1574621132849414100
  },


Configuration:

In schema.xml we configured as below:

Re: Arabic words search in solr

[mohanmca01]

Hi Steve,

thank you for your reply, it been quite long time to reply to you back.

i have tried what you suggested, and there were some improvements in terms
of searching and getting the results.

however, the team is facing some difficulty in searching using shortcut of
the indexed names which forced us to revert back the suggested changes..

below are the examples which we are facing:


-
*Example 1:*

*Indexed Text*
بنك مسقط - مركز الاتصال

*Searched*
مسقط الات

*Remarks of Example 1*
unable to get the indexed result unless I typed the two words fully (مسقط
الاتصال)


{
  "responseHeader": {
"status": 0,
"QTime": 0,
"params": {
  "indent": "true",
  "q": "businessNmBl:(مسقط الات)",
  "_": "1499758511717",
  "wt": "json"
}
  },
  "response": {
"numFound": 0,
"start": 0,
"docs": []
  }
}


-

*Example 2:*

*Indexed Text
*الطيران العماني - مركز الاتصال

*Searched*
الطير الات

*Remarks*
unable to get the indexed result unless I typed the two words fully (الطيران
الاتصال)


{
  "responseHeader": {
"status": 0,
"QTime": 2,
"params": {
  "indent": "true",
  "q": "businessNmBl:(طير الات)",
  "_": "1499758649600",
  "wt": "json"
}
  },
  "response": {
"numFound": 0,
"start": 0,
"docs": []
  }
}



Please be noted that the existing configuration (which we are facing
problems with Hamzzh (ء) and etc. )  on production is working with the above
examples. its not working only once we implement your suggested
configuration. 

Thanks in advance

Re: Arabic words search in solr

[mohanmca01]

Hi Stave,

Thanks for the support, I tried below cases but still i'm not able to get
the expected results.

Case 1 :

Input :  bizNameAr:شرطة + ازكي

Output : {

  "responseHeader": {
"status": 0,
"QTime": 1,
"params": {
  "indent": "true",
  "q": " bizNameAr:شرطة + ازكي",
  "_": "1489041466096",
  "wt": "json"
}
  },
  "response": {
"numFound": 4,
"start": 0,
"docs": [
  {
"id": "82",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة الداخلية
- - مركز شرطة إزكي",
"_version_": 1560298301338681300
  },
  {
"id": "63",
"bizNameAr": "شركة ظفار للتأمين ش.م.ع.ع - فرع ازكي",
"_version_": 1560298301325049900
  },
  {
"id": "56",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة شمال
الشرقية  -  - مركز شرطة إبراء",
"_version_": 1560298301319807000
  },
  {
"id": "79",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة شمال
الشرقية - - مركز شرطة إبراء",
"_version_": 1560298301335535600
  }
]
  }
}


In this case document id : 63,56,79 are not matching with the input,
where id 82 is the only correct in these results.



Case 2:


{
  "responseHeader": {
"status": 0,
"QTime": 3,
"params": {
  "indent": "true",
  "q": " bizNameAr:شرطة AND ازكي",
  "_": "1489043935549",
  "wt": "json"
}
  },
  "response": {
"numFound": 0,
"start": 0,
"docs": []
  }
}


if AND is given in between of the terms then no results are shown.

I saw your products in lucidworks website. Do you have any solr arabic
support customized product?

Thanks,

Re: Arabic words search in solr

[mohanmca01]

Hi Stave,

Thank for your continues investigation..

This has improved the search little bit, but am facing another issue where
am getting a record doesn't have a specific word in my query. 

Plz note that you have indexed only 9 records where i have shared you more
than 76 sample records (please refer to the earlier attachment
Arabic_Characters2.xlsx in Examples sheet) to index so you can reproduce the
issue. 

i.e. i searched with (bizNameAr: شرطة ازكي), and am getting:

{
  "responseHeader": {
"status": 0,
"QTime": 3,
"params": {
  "indent": "true",
  "q": "bizNameAr: شرطة ازكي",
  "_": "1488089550104",
  "wt": "json"
}
  },
  "response": {
"numFound": 4,
"start": 0,
"docs": [
  {
"id": "82",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة الداخلية - -
مركز شرطة إزكي",
"_version_": 1560298301338681300
  },
  {
"id": "63",
"bizNameAr": "شركة ظفار للتأمين ش.م.ع.ع - فرع ازكي",
"_version_": 1560298301325049900
  },
  {
"id": "56",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة شمال الشرقية 
-  - مركز شرطة إبراء",
"_version_": 1560298301319807000
  },
  {
"id": "79",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة شمال الشرقية -
- مركز شرطة إبراء",
"_version_": 1560298301335535600
  }
]
  }
}



the expected result is:   "id": "82",
  "bizNameAr": "شرطة عمان السلطانية - قيادة
شرطة محافظة الداخلية - - مركز *شرطة إزكي*",

as the above has both the words mentioned in the query (marked as Bold),
where the rest have the following:

"id": "63",
"bizNameAr": "شركة ظفار للتأمين ش.م.ع.ع - فرع ازكي"

it has only one word of the query (ازكي)

"id": "56",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة شمال الشرقية 
-  - مركز شرطة إبراء"

it has only one word of the query (شرطة)

"id": "79",
"bizNameAr": "شرطة عمان السلطانية - قيادة شرطة محافظة شمال الشرقية - - مركز
شرطة إبراء"

It has only one word of the query (شرطة)

where the above 3 records should not come in the result since already 2
words mentioned in the query, and only one record has these two words.


I would really suggest if we can give you a real-time demo on our system
with my Arab colleague so it can be more clear for you. let us know if we
can do that.

Thanks

Hi Stave,

As per your suggestion I added ICU folding filter and I re-indexed entire
solr data, but still am unable to find the expected results which i
highlighted earlier.

reproducing the issue.

Hi Steve,

Thanks for your continues investigation on this issue.

I added ICU Folding Filter in schema.xml file and re-indexed all the data
again. i noticed some improvements in search but its not really as expected.

below is the configuration changed in schema file:

-

   


 




  

-

attached the document for your reference where highlighted ones in red are
not working as expected.

Also, i have raised one point regarding Jquery autocomplete with unique
records..kindly let me know if you have any background on how to implement
the same.

Dear Steve,Thanks for investigating our problem. Our project is basically
business directory search platform, and we have more than 100+ K business
details information. I’m providing you some examples of Arabic words to
reproduce the problem. please find attached word file where i explained
everything along with screenshots. arabicSearch.docx
 
regarding upgrading to the latest version, our project is running on Java
1.7V, and if i need to upgrade then we have to upgrade Java, Application
Server JBoos, and etc. which is not that right time to do this activity at
all..!!

Re: Arabic words search in solr

Hi Steve,

Thanks for sharing the information. 

 I went through the solr references document which you shared in the link.
Your shared references document pointing to solr version 6.4.0.
The implemented Solr version in my project is 4.9.0.

As I mentioned earlier In my solr schema.xml I defined product Arabic name
field as below:

/*--*/
 
 









/*--*/


I am indexing the Arabic content using “text_ar” field type.

 
Characters
ا
أ
إ
آ
Shift key Considers for the above
Table 1

These are the example of characters where I’m facing the searching
difficulty.
 
Example Indexed words
ابرا
أبرا
إبرا
آبرا
Table 2

These an example of indexed words in Solr.
 
Searching word
ابرا
Table 3

Now my problem is, By searching for the above word(table 3) I should get all
indexed words in table 2 in the output.
 
Is Solr version 4.9.0 compatible with Arabic search or do I need to upgrade
to higher version?

Kindly, do let me know if I need to give an example of all characters since
I gave only for one character which is hamza with alef.

Thanks,
Mohan
