Find all nonsubstituted naphtalenecarboxylic acids.
 
     Query 1         Query 2   

     Query 1       HOME      Hitset 1     

The first aproach is to find 1-naphtalenecarboxylic acid and 2-naphtalenecarboxylic acid separately

  Q1    41 hits  

  Note:  
1-naphtalenecarboxylic acid
  Q2    25 hits  

  Note:  
2-naphtalenecarboxylic acid
  Q3    66 hits  
       .Q1 or .Q2       
  Note:  
putting the two parts together

 3. Of course hits will contain substances with isotopic substitution  

     Query 2       HOME      Hitset 2     

If you are too lazy to draw them both you can use this aproach

  Q1    29814 hits  
no implicit ring closures
  Q2    181 hits  
       mf = c11h8o2       
  Note:  
Reducing of first search with molecular formula, as a side effect this removes hits with deuterium substitution

 3. Of course hits will contain substances with isotopic substitution of carbons and oxygen  
 4. This curious molecule is also found because it has the same mf
