      See Also:

    • FULL

      static final int FULL
      Full structure search. (Prior to version 5.2 called EXACT.) Query and target must have the same heavy atom (non-H) network for matching. All other properties are otherwise evaluated the same way as substructure search. Please note that this search type is not suitable for equality check. For that, please use DUPLICATE search type. (Value=4)
      Since:
      JChem 5.2
      See Also:

    • DUPLICATE

      static final int DUPLICATE
      Duplicate search (formerly called perfect). Used for deciding absolute equality of molecular features (eg duplicate check before database insert). Equality is always subject to standardization in the database. Query features are not evaluated. (Value=5) For this search mode there is no search per minute license limitation in JChemBase, these searches are not counted.
      Since:
      JChem 5.2

      See Also:

    • STEREO_SPECIFIC

      static final int STEREO_SPECIFIC
      Option value constant for "specific" stereo search type. Stereo information is considered during searching when it is explicitly specified in the query structure. That is, a part of the query structure with no specified stereo configuration matches only to both stereo and non-stereo parts of the target.

      This is the default option for substructure search.

      See Also:

    • STEREO_IGNORE

      static final int STEREO_IGNORE
      Option value constant for "ignore" stereo search type. Stereo information is entirely ignored during searching.
      See Also:

    • STEREO_EXACT

      static final int STEREO_EXACT
      Option value constant for "exact" stereo search type. Stereo information is matched exactly. That is, a part of the query structure with no specified stereo configuration matches only to a non-stereo part of the target. Similarly, a wiggly tetrahedral center of the query matches only to a wiggly tetrahedral center of the target, not to specific R/S configurations.

      This is the default option for duplicate search.

      See Also:

    • STEREO_DIASTEREOMER

      static final int STEREO_DIASTEREOMER
      Option value constant for "diastereomer" stereo search type. The diastereomer targets of a given query structure are also matched.

      See Also:

    • HCOUNT_MATCHING_AUTO

      static final int HCOUNT_MATCHING_AUTO

      See Also:

    • HCOUNT_MATCHING_EQUAL

      static final int HCOUNT_MATCHING_EQUAL
      Option for H count matching. Means that a query atom with H count should only match a target atom with hydrogens (implicit or explicit) equal to the H count. This is the Daylight(smiles, smarts) behaviour.
      See Also:

    • HCOUNT_MATCHING_GREATER_OR_EQUAL

      static final int HCOUNT_MATCHING_GREATER_OR_EQUAL
      Option for H count matching. Means that a query atom with H count should only match a target atom with hydrogens (implicit or explicit) equal to or greater than the H count. One exception is H count = 0, which means no Hydrogens extra to those explicitly drawn. This is the MDL(sd, molfile) behaviour.

Basically, it is similar to the local stereo model, except when the target is symmetric. In the case of symmetric target, the matching is accepted regardless of the stereo information.

      static final int STEREO_MODEL_GLOBAL
      Option value constant of the global stereo search model, which considers global stereo information (global parity, global double bond stereo configuration, etc.). This model is suitable for duplicate search, as well as full structure and full fragment search, because in these cases, the whole stereospecific substructure is always represented in both the query and the target structures. Therefore, a symmetric atom/bond with stereo configuration may match to an unspecified stereo atom/bond.

      For example, the query structure C[C@](C)(C)C matches to CC(C)(C)C.

    • IMPLICIT_H_MATCHING_DEFAULT

      static final int IMPLICIT_H_MATCHING_DEFAULT
      Option value constant for default mode. Its value is IMPLICIT_H_MATCHING_ENABLED in almost every cases. There is only one exception: in case of duplicate search against a query table in a database the default value is IMPLICIT_H_MATCHING_DISABLED.

      static final int IMPLICIT_H_MATCHING_ENABLED
      Option value constant for indicate matching between implicit and explicit hydrogens. In case of duplicate search the sum of implicit and explicit hydrogens of the query atom and the sum on the matched target atom must equal.

    • IMPLICIT_H_MATCHING_DISABLED

      static final int IMPLICIT_H_MATCHING_DISABLED
      Option value constant for indicate matching of an explicit hydrogen only to another explicit hydrogen. The number of implicit hydrogens (of the matching atoms) are not checked.

    • IMPLICIT_H_MATCHING_IGNORE

      static final int IMPLICIT_H_MATCHING_IGNORE
      Option value constant to indicate that hydrogens, either explicit or implicit, are ignored during searching. Hydrogens having special properties (radical, charge, isotope or more/less than one bond) are still considered.
      Option CHARGE_MATCHING_IGNORE forces IMPLICIT_H_MATCHING_IGNORE in case of duplicate search. In case of duplicate search against a query table in a database IMPLICIT_H_MATCHING_IGNORE is switched to IMPLICIT_H_MATCHING_DISABLED. Hydrogens receive the excluded atom hit index HIT_EXCLUDEDQ in this case.
