# Non-topic queries (/docs/recipes/non-topic-queries)



Not every workflow starts from a topic id.\
For patent and research-article endpoints, you can query with non-topic filters.

## Example: research time series by term + date [#example-research-time-series-by-term--date]

```bash
curl -s "https://connect-api.trendtracker.ai/indicators/research-articles/time-series" \
  -H "content-type: application/json" \
  -H "x-api-key: $TT_API_KEY" \
  -d '{
    "resolution": "month",
    "query": {
      "type": "and",
      "filters": [
        {
          "type": "terms",
          "field": "title",
          "terms": ["large language model", "multimodal"]
        },
        {
          "type": "date",
          "field": "publishedAt",
          "start": "2022-01-01",
          "end": "2025-12-31"
        }
      ]
    }
  }'
```

## Example: patent proof points by term [#example-patent-proof-points-by-term]

```bash
curl -s "https://connect-api.trendtracker.ai/indicators/patents/proofpoints" \
  -H "content-type: application/json" \
  -H "x-api-key: $TT_API_KEY" \
  -d '{
    "take": 10,
    "query": {
      "type": "terms",
      "field": "abstract",
      "terms": ["graphene battery"]
    }
  }'
```
