# Chemical search

- [Structure drawing](https://chembl.gitbook.io/surechembl/chemical-search/structure-drawing.md)
- [Insert a SMILES, SMARTS, MOL, or Name Entry](https://chembl.gitbook.io/surechembl/chemical-search/insert-a-smiles-smarts-mol-or-name-entry.md)
- [Structure search type](https://chembl.gitbook.io/surechembl/chemical-search/structure-search-type.md)
- [Similarity Search, Tanimoto Coefficient and Fingerprint Generation](https://chembl.gitbook.io/surechembl/chemical-search/similarity-search-tanimoto-coefficient-and-fingerprint-generation.md)
- [Filter by molecular weight](https://chembl.gitbook.io/surechembl/chemical-search/filter-by-molecular-weight.md)
- [Search for structure in document section(s)](https://chembl.gitbook.io/surechembl/chemical-search/search-for-structure-in-document-section-s.md)
- [SMARTS search](https://chembl.gitbook.io/surechembl/chemical-search/smarts-search.md): SureChEMBL also accept SMARTS input. Here is a use of how they can be used.
