Hi guys,

i experiment with search phrases of german compound words. The testword is "kennenlernen" which consists of the two words "kennen" and "lernen".  
I configured the following settings to achive that i can find the word "kennenlernen" with the searchphrase "kennen".

Any ideas why this wont work or solutions for debugging the indexed terms?

Thanks a lot.

**Settings:**  
"analysis": {  
"filter": {  
"german\_stop": {  
"type": "stop",  
"stopwords": "_german_"  
},  
"german\_stemmer": {  
"type": "stemmer",  
"language": "light\_german"  
},  
"german\_compound\_filter": {  
"type": "dictionary\_decompounder",  
"word\_list": [  
"kennenlernen",  
"kennen",  
"lernen"  
],  
"min\_subword\_size": 2  
}  
},  
"analyzer": {  
"german\_mod": {  
"type": "custom",  
"tokenizer": "standard",  
"filter": [  
"lowercase",  
"german\_stop",  
"german\_normalization",  
"german\_stemmer",  
"german\_compound\_filter"  
]  
}  
}  
}

**Mapping:**  
"\_all": {  
"analyzer": "german\_mod"  
}

**Search with no hits:**  
"query": {  
"match": {  
"\_all": {  
"query": "kennen"  
}  
}  
}

**Search with one hit:**  
"query": {  
"match": {  
"\_all": {  
"query": "kennenlernen"  
}  
}  
}

Good Morning,

is there any possibility to debug / analyze the query process to find out why the query cant find a hit? Other ideas?

Thanks a lot.

Hi,

thanks for your help. I replaced the Compound Filter with a ngram Tokenizer for a generic solution, this works for me.

Thanks
