    - #### query

          public Iterator<javax.cache.Cache.Entry<?,?>> query(@Nullable
                                                              @Nullable String cacheName,
                                                              Collection<Object> params,
                                                              @Nullable
                                                              @Nullable IndexingQueryFilter filters)
                                                       throws IgniteSpiException

      Executes query.
      Specified by:
        `query` in interface `IndexingSpi`
      Parameters:
        `cacheName` - Cache name.
        `params` - Query parameters.
        `filters` - System filters.
      Returns:
        Query result. If the iterator implements `AutoCloseable` it will be correctly closed.
      Throws:
        `IgniteSpiException` - If failed.

    - #### store

          public void store(@Nullable
                            @Nullable String cacheName,
                            Object key,
                            Object val,
                            long expirationTime)
                     throws IgniteSpiException

      Updates index. Note that key is unique for cache, so if cache contains multiple indexes the key should be removed from indexes other than one being updated.
      Specified by:
        `store` in interface `IndexingSpi`
      Parameters:
        `cacheName` - Cache name.
        `key` - Key.
        `val` - Value.
        `expirationTime` - Expiration time or 0 if never expires.
      Throws:
        `IgniteSpiException` - If failed.

    - #### remove

          public void remove(@Nullable
                             @Nullable String cacheName,
                             Object key)
                      throws IgniteSpiException

      Removes index entry by key.
      Specified by:
        `remove` in interface `IndexingSpi`
      Parameters:
        `cacheName` - Cache name.
        `key` - Key.
      Throws:
        `IgniteSpiException` - If failed.

    - #### spiStart

          public void spiStart(@Nullable
                               @Nullable String igniteInstanceName)
                        throws IgniteSpiException

      This method is called to start SPI. After this method returns successfully kernel assumes that SPI is fully operational.
      Specified by:
        `spiStart` in interface `IgniteSpi`
      Parameters:
        `igniteInstanceName` - Name of Ignite instance this SPI is being started for (`null` for default Ignite instance).
      Throws:
        `IgniteSpiException` - Throws in case of any error during SPI start.

    - #### spiStop

          public void spiStop()
                       throws IgniteSpiException

      This method is called to stop SPI. After this method returns kernel assumes that this SPI is finished and all resources acquired by it are released.

      Note that this method can be called at any point including during recovery of failed start. It should make no assumptions on what state SPI will be in when this method is called.

      Specified by:
        `spiStop` in interface `IgniteSpi`
      Throws:
        `IgniteSpiException` - Thrown in case of any error during SPI stop.

    - #### setName

          public NoopIndexingSpi setName(String name)

      Sets SPI name.
      Overrides:
        `setName` in class `IgniteSpiAdapter`
      Parameters:
        `name` - SPI name.
      Returns:
        `this` for chaining.
