Using searchCriteria while searching attributes in magento 2.0

Question

Fetching attribute info, if I apply multiple filters in a single search criteria, it does not work. But in case of single filter it works perfectly.

Multiple filters HTTP request:

http://192.168.1.180/magento/index.php/rest/V1/products/attributes?searchCriteria[filter_groups][0][filters][0][field]=attribute_code&searchCriteria[filter_groups][0][filters][0][value]=color&searchCriteria[filter_groups][0][filters][0][condition_type]=eq&searchCriteria[filter_groups][0][filters][1][field]=attribute_code&searchCriteria[filter_groups][0][filters][1][value]=size&searchCriteria[filter_groups][0][filters][1][condition_type]=eq

Output: 
{
 "items": [],
 "search_criteria": {
 "filter_groups": [
 {
 "filters": [
 {
 "field": "attribute_code",
 "value": "size",
 "condition_type": "eq"
 },
 {
 "field": "attribute_code",
 "value": "color",
 "condition_type": "eq"
 }
 ]
 }
 ]
 },
 "total_count": 0
}

But when I hit the single filter one, I get results for both size as well as color.

Single filter:

http://192.168.1.180/magento/index.php/rest/V1/products/attributes?searchCriteria[filter_groups][0][filters][0][field]=attribute_code&searchCriteria[filter_groups][0][filters][0][value]=color&searchCriteria[filter_groups][0][filters][0][condition_type]=eq

UPDATE: Tried the in filter but still no results

{
 "items": [],
 "search_criteria": {
 "filter_groups": [
 {
 "filters": [
 {
 "field": "attribute_code",
 "value": "color,size",
 "condition_type": "in"
 }
 ]
 }
 ]
 },
 "total_count": 0
}

UPDATE 2: Tried "in" in different filters

{
 "items": [],
 "search_criteria": {
 "filter_groups": [
 {
 "filters": [
 {
 "field": "attribute_code",
 "value": "color",
 "condition_type": "in"
 },
 {
 "field": "attribute_code",
 "value": "size",
 "condition_type": "in"
 }
 ]
 }
 ]
 },
 "total_count": 0
}

UPDATE 3: Tried "in" filter in separate filter groups

{
 "items": [],
 "search_criteria": {
 "filter_groups": [
 {
 "filters": [
 {
 "field": "attribute_code",
 "value": "color",
 "condition_type": "in"
 }
 ]
 },
 {
 "filters": [
 {
 "field": "attribute_code",
 "value": "size",
 "condition_type": "in"
 }
 ]
 }
 ]
 },
 "total_count": 0
}

• Alex Paliarush: What is expected output and what you get?
• devdoe: updated the question
• devdoe: @AlexPaliarush did you find anything on this ?

Answer 1

Here is the fix for the "in" problem, this will probably be fixed in next release: https://github.com/magento/magento2/commit/65819d2f61a63e4fa9fc978220f8662ee5472791

Answer 2

The problem seems to be that the same field is used in 2 filters of the same filter group. In this particular case replace 2 eq filters with one in filter:

searchCriteria[filter_groups][0][filters][0][field]=attribute_code&searchCriteria[filter_groups][0][filters][0][value]=color,size&searchCriteria[filter_groups][0][filters][0][condition_type]=in

• devdoe: I tried but still no results '{ "items": [], "search_criteria": { "filter_groups": [ { "filters": [ { "field": "attribute_code", "value": "color,size", "condition_type": "in" } ] } ] }, "total_count": 0 }'
• Alex Paliarush: Request seems to be correct. What if specify separately 'in' filter with value 'color' and then value 'size'?
• devdoe: Edited question with both the API response
• Alex Paliarush: I meant searchCriteria[filter_groups][0][filters][0][field]=attribute_code&searchCriteria[filter_groups][0][filters][0][value]=color&searchCriteria[filter_groups][0][filters][0][condition_type]=in
• Alex Paliarush: Not sure you can track internal tickets, but you can create a ticket here and put as a note that MAGETWO-47450 and MAGETWO-47451 are created internally.
