SOLR or Query does not combine filters

Question

Ive 5 Entries like following

• spitze 1
• spitze 2
• spitze 3
• spritze 1
• spritze 2

Results are like following

&q=spitze~&defType=edismax

• spitze 1
• spitze 2
• spitze 3
• spritze 1
• spritze 2

&q=*spitze*&defType=edismax

• spitze 1
• spitze 2
• spitze 3

&q=(spitze~)-(*spitze*)&defType=edismax

• spritze 1
• spritze 2

&q=(spitze~)||(*spitze*)&defType=edismax

• spitze 1
• spitze 2
• spitze 3

so why does this or statement not work. it thought it would combine both and give me all 5 results. Where is my error in this query...
