Question

I followed the below link to generate the input for item affinity receipe

]()

Input

```

```

But I want to provide multiple input for skills HTML, CSS, REACT_JS ,  and also another attribute TITLE = SDE, EXPERIENCE_RANGE_IN_YEARS_START = 5, EXPERIENCE_RANGE_IN_YEARS_END =10.

How to give multiple key and mutliple values in input itemAttributes in single query ?
Is it possible to get output based on multiple parameters

Accepted Answer

1. The expressions for batch segment item-attribute affinity recipe do not support range expressions or logical 'OR'. Currently, the supported querys are as the following example:

{"itemAttributes": "ITEMS.genres = \"Comedy\" AND ITEMS.genres = \"Action\""}

{"itemAttributes": "ITEMS.genres = \"Comedy\""}

{"itemAttributes": "ITEMS.genres = \"Horror\" AND ITEMS.genres = \"Action\""}

2. Batch segment input expressions support only the "=" symbol for equality for string matching

3. The "OR" operator, it can be splitted into two queries as follows:

{ "itemAttributes" : "ITEMS.genres=\"Comedy\""}

{ "itemAttributes" : "ITEMS.genres=\"Horror\""}

Answer

Hi,

Yes, it is possible to provide multiple attributes and their corresponding values as input to the itemAttributes parameter in a single query. You can use the AND logical operator to combine multiple conditions.

Here is an example of how you can provide multiple conditions to the itemAttributes parameter in multiple queries:

{"itemAttributes": "ITEMS.SKILLS = \"HTML\" AND ITEMS.TITLE = \"SDE\"}

In this example, we are combining multiple conditions using the logical operators AND . The query will return items that have skills in HTML and have the title "SDE".

You may refer [official docs](https://docs.aws.amazon.com/personalize/latest/dg/batch-data-upload.html ) for details if you want.

Hope it helps.
