    See Also:
    
    JChem chemical database concepts, Constant Field Values
  - 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, SUBSTRUCTURE, JChem chemical database concepts, Constant Field Values
  - 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:

    See Also:

    Constant Field Values
  - STEREO_EXACT
```
static final int STEREO_EXACT
```
    Equality is needed in stereochemistry. ("All stereo info is exactly the same.") It mainly has an effect when the query has no stereo information: it only matches non-stereo target. Similarly, a query with a wiggly tetrahedral center will only match wiggly tetrahedral center, and not specific R and S configurations. If STEREO_SPECIFIC is set, non-stereo query matches both nonstereo and stereo target.
    
    See Also:
    
    Constant Field Values
  - STEREO_DIASTEREOMER
```
static final int STEREO_DIASTEREOMER
```
    The diastereomers targets of a given query structure are also matched. This means that it is only required that if a query atom has stereo information, the target atom should have as well but the two configurations are treated the same.

    See Also:
    
    Constant Field Values
  - 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.

  - STEREO_MODEL_GLOBAL
```
static final int STEREO_MODEL_GLOBAL
```
    Option value constant to use global stereo information (global parity, global double bond stereo configuration, etc). This value is suitable for duplicate, full and full fragment searches, as in these cases the full stereospecific environment is always available for both the query and target structures. (Therefore a symmetrical atom/bond with stereo configuration may match to an unspecified strereo atom/bond. For example, C[[email protected]](C)(C)C matches CC(C)(C)C.)

```
static final int IMPLICIT_H_MATCHING_DEFAULT

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.
