Due to architectural differences, the LINQ syntax presents some particularities in the [Devo APIs](https://devodocs.atlassian.net/wiki/spaces/latest/pages/95128251) and the [search window](https://devodocs.atlassian.net/wiki/spaces/latest/pages/95202447) of the Devo app.
Therefore, keep in mind that copying a LINQ query from the search window and pasting it into an API request, or vice versa, might not work. Before examining the differences explained below, you can visit [Build a query using LINQ](https://devodocs.atlassian.net/wiki/spaces/latest/pages/95191261) to know the standard procedures when working with LINQ.
> ⚠️ **Alerts API**
> ⚠️
> ⚠️ Note that due to technical reasons, the [Alerts API](https://devodocs.atlassian.net/wiki/spaces/latest/pages/95128644) is the only API that uses the LINQ syntax used in the [search window](https://devodocs.atlassian.net/wiki/spaces/latest/pages/95202447) of the Devo app. This is indicated in the different sections below.
## Mlevalmodel operation
`mlevalmodel` operation is not supported in search window. Use this operation in APIs when you want to work with models you uploaded in Model Management.
| **Search window** | **Devo APIs** |
| --- | --- |
| `Not supported` | Query examples:
```
from "datatable"
select "fields"
mlevalmodel("domain", "ModelName", "ModelFields") as "NameNewField"
```
Example:
```
from demo.ecommerce.data
select
split(referralUri, "/",2) as domain,
float(lenght(domain)) as lenght
shannonentropy(domain) as entropy
float(countbyfilter(domain, "aeiuoAEIOU")) as p_vowels,
mlevamodel("example_domain", "example_test", lenght, entropy, p_vowels) as prob
ifthenelse(prob>0.8, "dga", "legit") as type
