Reducing heap space consumption for large dictionaries?

[Mark Schoy]

Hi,

in my index schema I has defined a
DictionaryCompoundWordTokenFilterFactory and a
HunspellStemFilterFactory. Each FilterFactory has a dictionary with
about 100k entries.

To avoid an out of memory error I have to set the heap space to 128m
for 1 index.

Is there a way to reduce the memory consumption when parsing the dictionary?
I need to create several indexes and 128m for each index is too much.
