The issue you're encountering might be due to the way Shopify's Search API handles non-space-separated words. When the vendor name doesn't have a space, the search query may treat the vendor name as a single token and thus not return the expected results.
In your case, you can try enclosing your vendor name in quotes, like so:
{
orders(first: 10, query: "lineItems.product.vendor:\"MyVendor\"") {
edges {
node {
id
updatedAt
createdAt
lineItems(first: 10) {
edges {
node {
id
title
variant {
id
title
}
product {
vendor
}
}
}
}
}
}
}
}
This will explicitly treat "MyVendor" as a single string.
For dealing with the issue of only getting 30 orders back at a time, you can paginate your results using cursor-based pagination. You can use the `after` argument and pass the cursor of the last edge in the previous page to get the next page of results. Here is an example of how to do that:
{
orders(first: 10, after:"<cursor>", query: "lineItems.product.vendor:\"MyVendor\"") {
pageInfo {
hasNextPage
}
edges {
cursor
node {
id
updatedAt
createdAt
lineItems(first: 10) {
edges {
node {
id
title
variant {
id
title
}
product {
vendor
}
}
}
}
}
}
}
}
Here, replace `<cursor>` with the cursor of the last item from the previous query. `pageInfo` tells you whether there are more pages to fetch. If `hasNextPage` is true, you can take the `cursor` of the last edge in `edges` and use that as the `after` argument in the next query to fetch the next page.
Try this out and see if it works for your purposes!
